Abstract: A control unit includes an excessive output suppression control unit which suppresses an excessive output by reducing a current command value from a host control apparatus. A control signal output unit obtains a motor control signal by adding a reduction amount of the current command value to the current command value. The excessive output suppression control unit includes: an oil pressure estimating unit which estimates oil pressure based on a current and a rotating speed of the electric motor; and a current command value correction amount calculating unit which compares outputs the reduction amount of the current command value if the estimated oil pressure is higher than target oil pressure. One of the target oil pressure and the estimated oil pressure compared by the current command value correction amount calculating unit is corrected based on oil temperature information.

Abstract: A diverter assembly for a shower tub includes a housing having an inlet for receiving fluid and first and second outlets for discharging fluid. An endless advancement structure includes a flow plate fixed to the housing and a gearing arrangement rotatable relative to the flow plate. The flow plate includes a first opening in fluid communication with the first outlet and a second opening in fluid communication with the second outlet. The gearing arrangement includes third openings in fluid communication with the inlet. A handle is coupled to the gearing arrangement for selectively rotating the gearing arrangement in a single direction relative to the flow plate to alternate between placing the gearing arrangement in a first condition aligning one of the third openings with the first opening and placing the gearing arrangement in a second condition aligning one of the third openings with the second opening.

Abstract: A valve which controls the movement of pressurized fluid through a passage, the regulation of which is determined by the application of a centrifugal force generated by the rotation of the valve about a fixed axis

Abstract: A governor valve assembly for regulating hydraulic pressure by utilizing centrifugal force developed by the output shaft of a vehicle transmission when the output shaft is rotated has a first governor valve adapted for two-stage pressure regulation and a second governor valve for adapted for a single stage of pressure regulation disposed separately in a governor body supported on an output shaft. An output port of either one of the valves is communicated with a feed port of the other through a passageway in the governor body in order to obtain a three-stage hydraulic pressure characteristic.

Abstract: A vehicle wheel-tire assembly wherein the tire has a low inflation pressure (large tire footprint) in a low vehicle speed range, and a large inflation pressure (small tire footprint) in a high vehicle speed range. The tire is partitioned into a series of circumferential compartments, with each compartment being provided with a valve mechanism for introducing air into the compartment and/or withdrawing air from the compartment as needed to maintain desired inflation pressures in the different vehicle speed ranges. The system is contained entirely in the wheel-tire assembly; no external air compressors or control valves are utilized.

Abstract: In a pneumatically powered portable tool there is provided a speed governor and an overspeed safety device the purpose of which are to ensure a predetermined maximum speed by controlling the air inlet flow to the motor. A cup-shaped shell insert (28) is detachably mounted in the housing (10) to form with the latter an air supply passage (58) and to support the valve means (51,53) of the overspeed safety device. The top surface of the shell insert (28) is exposed through an aperture (57) in the housing (10) and carries the maximum speed marking of the tool.

Abstract: A governor control valve is provided in which governor output pressure is varied in response to variations in vehicle speed by moving a valve member radially with respect to a ported shaft carried with a driven housing which drivingly carries a centrifugal force responsive weight mechanism. The ball valve and the weight mechanism are connected by a yoke member whose mass center is aligned with the axis of rotation of the housing and shaft.

Abstract: A timing and control mechanism for a centrifuge comprising a piston to which is attached a cam having cam surfaces which interact with flexible tubing to control the rate of flow through the tubing. The velocity of the piston in the centrifugal force field is determined by the resistance to flow of fluid which the piston displaces. The movement of the cam is therefore a measure of the speed and duration of the centrifugal force.

Abstract: A fluid pressure governor adapted to sense the driven speed of an automatic transmission torque output shaft and to develop a speed signal that may be used by an automatic transmission control circuit in conjunction with a torque demand or engine torque signal to control automatic ratio changes in a transmission mechanism as torque is delivered from a vehicle engine to vehicle traction wheels. Provision is made for interrupting the speed signal distribution to the control elements of the transmission mechanism when deceleration of the vehicle exceeds a critical value thus causing the transmission mechanism to downshift to higher torque ratios during rapid deceleration of the vehicle and thereby eliminating any tendency of the vehicle engine to stall or to malfunction as a result of braking of the vehicle.

Abstract: A regulating device is comprised of a shaft which is driven at a speed of revolution proportional to the speed of an automobile, and a duct provided in the shaft and connected for fluid transmission from a pressurized fluid source and the control means for the automatic automobile transmission. The duct has two pressure control openings, each of which has a pressure release valve. The first of the pressure release valves is loaded with a relatively large-mass flyweight mounted to one axial end of the shaft and, upon rotation of the shaft, urges its respective pressure release valve toward the closing position. The other pressure release valve is biased closed by a spring and is loaded with a relatively small flyweight which, upon the rotation of the shaft, urges its respective pressure release valve toward the closing position. The present invention includes a third flyweight which acts on the spring to increase the closing force exerted on the second flyweight.

Abstract: A governor is disclosed in which dust which may comprise steel powder, fine particles of sand and so on will be removed from a hydraulic working fluid by subjecting the working fluid to centrifugal force. A fluid passage for the working fluid is formed in a housing of the governor and a chamber communicates with the passage at the opening. The fluid passage has an opening located such that dust contained in working fluid will enter into the chamber through the opening while the housing is rotating. Within the chamber working fluid will be stagnant and dust sedimented.

Abstract: A pair of piston valve members are slidably mounted in a housing rotatably engaging the output shaft of the automatic transmission. A first piston valve moves freely under the influence of centrifugal force within the housing to throttle line pressure from a pump in the transmission to a governed pressure level used for performing shifting functions within the transmission and the second piston valve member is spring biased against the influence of centrifugal force to prevent its movement under the influence thereof until a predetermined output shaft speed is reached whereupon it throttles the line pressure supplied by the transmission pump and directs it to a portion of the first piston valve to vary the operation thereof upon further increases in output shaft speed.

Abstract: A governor valve assembly is disclosed for automatic transmission units including first and second valve members which are provided in a rotating governor body so as to be telescopically fitted together. The first and second valve members are arranged on diametrically opposite sides of the rotating axis of the governor body, and cooperate with one another so that when the rotating speed of the governor body reaches a preselected level, a governor pressure is produced and delivered from the assembly.
