摘要： A turbocharger system comprises a first relatively small high-pressure (HP) turbocharger and a second relatively large low pressure (LP) turbocharger. The turbine of the LP turbocharger is connected in series downstream of the turbine of the HP turbocharger. A first exhaust bypass flow passage provides a bypass flow path around the HP turbine. A second exhaust bypass flow passage provides a bypass flow path around the LP turbine. A rotary valve is located at a junction of the first and second bypass flow passages and a first exhaust gas flow passage. The rotary valve comprises a valve rotor which is rotatable selectively to permit or block flow to the LP turbine and to permit or block flow to the first and second bypass paths.

摘要： A directional control valve has a first fluid path extending between first and second ports and a second fluid path between second and third ports. A spherical valve member moves between an open position in which the valve member is displaced from a first valve seat so that the first fluid path is open and is sealed against a second valve seat so that the second fluid path is closed and a closed position in which the valve member is sealed against the first valve seat so that the first fluid path is closed and displaced from the second valve seat so that the second fluid path is open. The valve member is biased towards the closed position by opposed first and second biasing members of unequal loading. An actuator can move the valve member from the closed position to the open position against the unequal loading.

摘要： Disclosed is an energy-recycling hydraulic control main valve, which is provided with end covers, a valve core, a left one-way valve and a right one-way valve; the left one-way valve is composed of a left valve seat, a left cone valve core and a left spring; a conical surface of the left cone valve core is closely attached to a left conical surface of the valve core by the spring force; the right one-way valve is composed of a right valve seat, a right cone valve core and a right spring; and a conical surface of the right cone valve core is closely attached to a right conical surface of the valve core by spring force. The hydraulic main control valve can not only limit the falling speed of a piston, but use the potential energy generated by the gravity action on the piston, thereby achieving energy recycling.

摘要： This invention concerns a slider valve in which a sliding block (10) of generally square cross-section (the corners of which are rounded) is a close sliding fit in a circular bore (14) in a body member (16). At right angles to the axis of the bore (14) and communicating therewith are ports (18) each of which is similar. Each port includes a smaller diameter section in which is located a cylindrical pad (22) of a plastics material having a fluid passage (24) formed therethrough to allow fluid from a tube (26) encased within a metal sheath (28) to pass into a port (30 or 32) in the block (10) if the latter is registering therewith. Two or more such valves can be joined by axially aligning and securing together the cylindrical body member 16 and the end of one block (10) will act on the end of an adjoining block (10) in an adjoining valve.The movement of the block or blocks axially relative to the body member (16) is effected by means of an actuator (52, 54) at one end of the body member (16) and a similar actuator or spring is provided at the opposite end to return the block (10) to its original position.The two extreme positions allow the bores (30, 32) in the block (10) to be aligned with selected ones of the ports (18).Pre-alignment and setting up of each valve or of a plurality of valves arranged in series, can be easily effected by adjusting the relative positions of the bodies (16) and locking the adjusted positions. (FIGS. 1 and 2).

摘要： A servo valve controls the rate and direction of flow of a hydraulic fluid from a fluid power system to impart reciprocating motion to the piston of a hydraulically driven motor. An outer sleeve member of the servo valve has entry and exit ports connected to the source of fluid power and motor control ports connected to the hydraulically driven motor. A slider member is positioned within a cylindrical opening through the sleeve member and includes fluid chambers within the slider for alternating the direction of fluid flowing to the hydraulically driven motor by rotating the slider member. The rate of fluid flow is controlled by the lateral movement of the slider within the sleeve member.
