摘要： The invention relates to a fuel feed pump for a fuel injection pump for internal combustion engines, having a pair of gear wheels that mesh with one another and are driven to rotate in a pump chamber. The pair of gear wheels pump fuel out of an intake chamber that communicates with a supply tank along a feed conduit, formed between the end face of the gear wheels and the circumferential wall of the pump chamber, into a pressure chamber that communicates with the fuel injection pump. One gear wheel is secured to a shaft is driven to rotate by means of a drive element that engages the shaft, wherein the drive element can be connected to the shaft by an overload safety device.

摘要： An oil pump effects a pumping action to deliver oil from an inlet port to a first outlet port and also to a second outlet port. An oil supply passage is connected to the second outlet port. A regulator value has a bore, a spool disposed in the bore, a pressure chamber, and a pressure admission port connected to the oil supply passage and communicating with the pressure chamber. A branch passage connected to the oil supply passage opens to the bore. The regulator valve also has relief port connected to the inlet port and opening to the bore, and a transfer port connected to the first outlet port. The spool disposed in the bore is moveable responsive to pressure within the pressure chamber between a first position in which the transfer port is connected to the branch passage and a second position in which the transfer port is connected to the relief port.

摘要： To restrain the swinging of a movable displaceable cam ring and a spool of a control valve and to suppress pulsation on the discharge side of a variable displacement pump. In the variable displacement pump, a variable metering orifice (40) is provided midway in discharge-side passages (24, 29, 43, 44, 45) extending from a pump chamber. A spool-type control valve (30) is operated with the fluid pressure on the upstream and downstream sides of the orifice to control the fluid pressure supplied to fluid-pressure chambers around the cam ring in accordance with the flow rate of the fluid discharged from the pump chamber. A single or multistage throttle portion including throttles (50, 51, 52) is provided in at least one of fluid passages (46, 47) for communicating the upstream side of the orifice to one chamber of the valve, and fluid passages (35, 19b) for communicating the one chamber to the first fluid-pressure chamber as the valve operates.

摘要： There is provided a control device for a vane type variable displacement pump. The control device eliminates the need of a hydraulic cylinder to control the eccentricity of a cam ring of the vane pump. A pressure difference between a second chamber and a high pressure side of the pump first chamber on a low-pressure side of the vane pump is utilized to determine the eccentricity of the cam ring. A regulator valve is connected to the first chamber and with the second chamber in order to allow or prevent communication between the two chambers. A spring is also provided to always force the cam ring in a direction so as to make the eccentricity of the cam ring larger.

摘要： A control device for a positionable pump has a body with inner and outer diameters eccentric to each other mounted in the pump housing bore and is actuated by hydraulic pressure in one angular direction. An opposing spring force acts in the opposite direction for controlling the angular position of the body. A controlled member is nested in the inside diameter of the body and a power rotated control member is nested within and drivingly engages the controlled member and is eccentric thereto, being a pair of pumping elements. The pump elements being gerotor or vane type elements utilized to pump fluids and which depend upon the eccentric position of their relative components for a fixed delivery of fluids. The body is controlled in infinitely angular positions relative to the pump housing to regulate the eccentric position of such pumping elements and thereby controlling the volume output of said pump elements relative to the demand of the external system increasing and diminishing needs.
