摘要： A pneumatic tool includes a rotor rotatably received in a housing, a driving shank coupled to the rotor, for being rotated by the rotor and by a pressurized air and having one end for driving a fastener. A pressure releasing device may release the pressurized air after the fastener has been tightly threaded onto the object to be fastened. A fluid container is rotatably received in the housing and coupled to the rotor, for partially receiving the driving shank. The driving shank has one or more paddles for being frictionally driven by the container and by the fluid. A pole is slidably engaged through the rotor, and actuated to release the pressurized air when the fastener has been tightly threaded onto the object.

摘要： A rotary fluid pressure device is disclosed of the type utilizing a gerotor gear set (13) and an output shaft assembly (45) including a spool valve (49). The device includes a housing (11) defining inlet and outlet ports (21 and 23). The spool valve and housing cooperate to define a lubrication fluid chamber (59). Torque is transmitted from the gerotor set to the output shaft by a dogbone shaft (61) having a rearward spline connection (65, 69) to the gerotor, and a forward spline connection (63, 67) to the output shaft. The spool valve defines a pair of annular grooves (71, 73) in communication with the ports and a pair of check valve assemblies (91, 93) to permit flow of lubrication fluid from the lubrication chamber into whichever of the annular grooves is in communication with the outlet port. The resulting lubrication circuit insures a good flow of lubrication through both of the spline connections, in either direction of operation of the device, and further insures that contamination particles are carried from the spline connections to the outlet port without having to pass through severe flow restrictions which can trap such particles.

摘要： An energy recovery system for wheeled vehicles is characterized by a compressor/expander which operates as an expander in the run mode to assist the engine in driving the vehcile and as a compressor in the braking mode to store braking energy. A heat exchanger, a boiler drum, and a flash chamber transfer heat from the vehicle exhaust to a working fluid for generating high and low pressure vapor. The boiler drum stores heated and vaporized liquid and supplies high-pressure vapor to the inlet port of the compressor/expander during the run mode. The flash chamber supplies low-pressure steam to the inlet port of the compressor/expander during the braking mode. Storage tanks are provided for storing and passing low-pressure vapor to the input of the compressor/expander during the run mode.
