    摘要： A hot-water supply system 1 comprises a temperature responsive valve 61 provided in a first bypass passage 60, an orifice 31 provided in a second bypass passage 30, a flow rate sensor 24 provided in a water supply passage 11 downstream from a connection point with the second bypass passage 30, a circulating pump 33 provided in the water supply passage 11 downstream from the connection point with the second bypass passage 30, and a controller 4. The controller 40 operates the circulating pump 33 and executes circulation heating operation for operating a burner to heat the hot water circulating through a circulation circuit 80, when a flow rate detected by the flow rate sensor 24 is equal to or more than a specified flow rate.

    摘要： A variable oil pump capable of rapidly ejecting a required amount of working fluid using an oil pressure of the working fluid generated according to an engine RPM, and improving a lubrication effect to improve engine efficiency. Also described is a variable oil pump, in which a gap is provided between a plunger and a cylinder to easily operate the plunger using an oil pressure output from an oil pump, enabling more rapid supply of a required amount of oil using an oil pressure varied according to variation in an engine RPM. A variable oil pump is described in which the plunger is perpendicularly operated with respect to a flow direction of the working fluid, such that the plunger can be operated in a direction in which a pressure of the working fluid is applied to operate the oil pump.

    摘要： A method of producing treated liquid hydrocarbons. The method begins by pressurizing a latex in a pressure vessel. This is followed by flowing the latex from the pressure vessel into a pipeline containing liquid hydrocarbons to produce treated liquid hydrocarbons. In this embodiment the latex comprises a drag reducing polymer.

    摘要： A device and method for chemicals to be fed into a water system, treating the water system as it enters, for example, a fire protection mains and/or fire protection systems (FPS) to protect and maintain the longevity of the water system preventing damages to the water system or enhancing the operation characteristics of the system. This device is a treatment system that may be installed as a portable or permanent device with chemicals such as, corrosion inhibitors, wetting agents, polymeric dispersants, biocides, biostats or other water chemical enhancing effects with means for injecting the chemicals into th fire protection system or a bypass feed system (20) utilizing the fluid means without the need for any electricity. Activation of the pump(1) occurs when water enters the FPS mains and FPS sprinkler system from an outside source. Valving (22, 24) is included to isolate the pump and drums, storage tank to prevent backflow from the FPS.

    摘要： A by-pass fuel system configured so that in the event diesel fuel has waxed and/or ice crystals have formed such that the fuel cannot pass easily through the fuel pump fuel strainer, the diesel fuel is selectively able to pass through an auxiliary fuel port via a by-pass valve, thereby ensuring adequate fuel flow to the diesel engine. Return fuel heated by the engine is preferably directed directly onto the fuel pump fuel strainer to help dissolve the waxing and crystallization. An auxiliary coarse fuel strainer optionally provides coarse fuel straining of the by-passed fuel.

    摘要： A damping force variable valve includes a retainer having a main body connected at a central portion thereof to a high pressure part or portion of a shock absorber and having an outer peripheral region enlarging outwardly, and a spool rod integrally extending from the central portion and formed at a center thereof with a hollow portion having a spool inserted therein. The variable valve further includes a main disc disposed adjacent the retainer, a solenoid unit provided adjacent the spool rod and including a push rod for moving the spool when electrical power is applied, and an operating block installed adjacent the solenoid unit and including an enlarged portion coupled to the outer peripheral region of the main body.
