摘要： An exhaust gas heat exchanger for transferring heat from the exhaust gases of an engine to its liquid coolant, thereby increasing the rate of heating of the coolant. The heat exchanger according to this invention provides a regulated rate of heat transfer despite changes in the temperature of the exhaust gases. The exchanger includes a heat pipe with an evaporator and condenser portion. The evaporator portion is exposed to exhaust gases; thus heating the working fluid in the heat pipe, and the condenser portion is in thermal communication with an engine coolant heater. In order to accommodate a broad range of exhaust gas temperature, the heat exchanger includes means for storing the working fluid such that the quantity of the working fluid transferring heat from the evaporator to the condenser portions can be varied. This system enables substantially all of the working fluid in a liquid phase to be removed from the evaporator (i.e. a complete drying out) when the temperature of the evaporator approaches the upper limit of its operating range.

摘要： An improved heat pipe comprising a duct having disposed at opposite ends thereof an evaporator with wick-lined hollow fins in the form of extended corrugations thereon, and operable to supply heat to the evaporator comprised of a gas combustor having an internal volume for containing the evaporator and combustion air for supply to a combustion chamber located therein; a wick capable of transporting liquid by capillary action lining substantially all internal surfaces of said heat pipe; an external heat sink operable to remove heat from the condenser; and a heat transport medium contained by said heat pipe. The evaporator is further comprised of a coarse porous material lining and completely filling the spaces within the hollow fins open to the evaporator for increased structural stiffness and ease of fabrication; and a porous mass completely filling the evaporator for increased compressive strength. The coarse porous material and the porous mass are sufficiently porous to allow vapor to flow through each with a minimum of obstruction.

摘要： A system and method of speed and power control for an engine in which speed and power of the engine is controlled by modulation of the load torque. The load torque is manipulated in order to cause engine speed, and hence power to be changed. To accomplish such control, the load torque undergoes a temporary excursion in the opposite direction of the desired speed and power change. The engine and the driven equipment will accelerate or decelerate accordingly as the load torque is decreased or increased, relative to the essentially fixed or constant engine torque. As the engine accelerates or decelerates, its power increases or decreases in proportion.

摘要： A heat pipe system particularly adapted for use with finned evaporators. In accordance with this invention, a separate liquid working fluid return conduit is provided which communicates with a liquid working fluid distribution means for distributing working fluid uniformly to all of the evaporator fins. Means are also provided in accordance with this invention for storing excess liquid working fluid either as a column of liquid within the liquid return pipe which is developed by a flow restrictor, or by selecting a distribution wick from a material having low capillary pressure which enables it to become saturated with liquid working fluid.

摘要： An external heating system for a heat engine such as a Stirling cycle engine which permits thermal energy to be provided by solar energy or fuel combustion sources. The system employs a complexly shaped heat pipe evaporator section having an enclosed cavity for receiving solar energy and another section forming hollow fins which is exposed to hot combustion gasses. Accordingly, either heat source may be used to evaporate working fluid within the heat pipe which is transferred to the associated heat engine.

摘要： An energy recovery system permits recovering energy from fumes. The system employs a heat engine such as a Stirling engine, and a supplemental combustible fuel. A combustor receives the paint fumes as well as the supplemental fuel from a fuel supply. The fuel supply includes a fuel throttle regulating the fuel mass flow rate. An air blower provides air to the combustor. The heat engine includes a heater receiving heat from the combustor. A temperature sensor detects the temperature of the heater, while a controller operatively controls the fuel throttle to vary the fuel mass flow rate based on the temperature of the heater.

摘要： A working gas pressure equalization system for a multiple-cylinder, double-acting hot gas engine such as a Stirling engine of the type having a plurality of pistons reciprocatable within the cylinders defining a plurality of generally isolated cycle volumes of a working gas separated by the pistons. The equalization system incorporates passages through the piston connecting rods which connect between a space between piston rings and an equalization volume defined between a pair of sliding rod seals. This volume is defined by portions from each of the cylinders and is connected with individual cycle volumes by a valve, such as a one-way check valve. When a pressure is experienced in one of the cycle volumes different from the minimum pressure maintained and the equalization volume, minute gas leakage across the piston rings enables pressure among the volumes to be equalized.

摘要： A heater assembly for a heat engine designed to utilize solar energy and heat produced by combustion of a fuel such as natural gas. A receiver housing allows concentrated solar energy to be directed through a receiver aperture into a receiver chamber. Inner and outer arrays of heater tubes within the receiver chamber absorb the solar energy and transfer heat to working fluid in the heater tubes. A burner within the housing produces combustion gases which circulate past the heater tubes and transfer heat to the working fluid. The heater tubes form an opaque surface to solar energy and have uniform gaps which allow heated fluid to be passed between adjacent heater tubes. A precise three-dimensional mathematical description for the centerlines of the heater tubes which maintains uniform gaps between adjacent heater tubes is disclosed.

摘要： Improved lubricant control assemblies for reciprocating piston rods of an engine which prevent crankcase lubricant intruding into the cylinders and fluid from the cylinders from escaping into the crankcase. Each assembly comprises a tubular scraper fitting closely onto a piston rod and yieldably mounted within the bore between cylinder and crankcase through which the piston rod extends. The yieldable mounting is by means of a compliant housing. The compliant housing allows the scraper to be displaced radially and thereby follow limited radial displacement of the piston rod while maintaining substantially full effectiveness of the scraper's action on the reciprocating piston rod. The scraper is urged into forceful contact around the piston rod by means of a crown spring which is supported on a tubular part which attaches to the compliant housing. The compliant housing comprises an outer ring portion which is threaded into the bore to mount the assembly on the engine and an inner ring portion which attaches to the tubular part. One or more intermediate ring portions may be included in the compliant housing. Each ring portion joins to its immediate ring portion(s) at only one axial end with the points of joining alternating axially from each ring to the next. A disclosed embodiment for the compliant housing comprises a one piece nylon part.
