摘要： A fluid power control system (17) having an improved control valve (20) providing reduced regulated pressure fluid selectively from a high pressure pump supply (P) or the fluid motor (10) under conditions wherein the pump supply has failed to supply the desired pressurized fluid. The system utilizes a control valve (20) having a spool (29) provided with first transfer passage (41) and second transfer passage (42). The first transfer passage is adjustably throttled as a result of movement of the spool relative to an adjacent inlet port (37) and the second transfer passage (42) is adjustably throttled by movement of the spool relative to an adjacent inlet port (38). Inlet port (37) is connected to the high pressure fluid supply P and inlet port (38) is connected to the head end (13) of the cylinder (11) of the fluid motor through a check valve (44). Valve (20) provides selective pressure regulated fluid through an outlet port (36) thereof either from the pressurized fluid supply P when that apparatus is functioning or from the fluid motor in the event of a failure of the fluid supply. In each case, the valve provides the fluid at a desired operating pressure. The pressure regulated fluid may be used to operate a pilot valve (22) controlling a main valve (14) for adjustably positioning the piston (12) of the fluid motor.

摘要： An integral coupling is provided for transmitting torque from a flexible driveplate mounted to an engine flywheel. The coupling has a base portion which is fixed to the flexible driveplate and a shaft portion which extends axially away from the base portion. The shaft portion has male splines which are shaped to be matably received in a female splined connector of a rotatable member. In particular, the female splined connector is formed in the hub of a gearbox input pinion driving a gearbox which, in turn, drives a hydraulic pump supplying hydraulic pressure to systems of a gantry crane. The integral coupling permits axial movement at the male splined end which is distally located relative to the flexible driveplate. The integral coupling provides improved performance over a conventional two-piece coupling having a male--male splined shaft which matably fit the base portion mounted to the flexible driveplate.

摘要： A refrigeration compressor assembly includes a motor compressor mounted within a hermetically sealed shell with a sump area at the bottom containing a lubricating oil. An oil stirrer is secured to the crankshaft below the motor components and includes a hub secured to the crankshaft and a conical, smooth, imperforate skirt extending outwardly and downwardly below the oil surface. The oil stirrer is formed of a plastic insulating material which does not permit the formation of eddy currents within the oil stirrer from the motor flux leakage and whose surface is not wetted by the lubricating oil.
