摘要： A control device for a hyudraulic friction clutch for a motor vehicle, wherein a piston is moved by a pressurized fluid supplied to a pressure chamber, to effect frictional engagement between driving and driven rotary members, and a proximity shut-off valve is disposed in the piston, for permitting the fluid to be discharged from the pressure chamber through a discharge passage when the piston has reached a ready-to-operate position from which the piston is moved to start the frictional engagement. The control device includes a hydraulic pressure source generating a predetermined line pressure, a pressure adjusting device for adjusting the line pressure to a controlled clutch pressure, a clutch control valve for applying the controlled clutch pressure to the pressure chamber to advance the piston for effecting the frictional engagement of the rotary members, and a controller for commanding the pressure adjusting device to adjust the line pressure to a predetermined lower level, when the controller commands the clutch control valve to supply the pressurized fluid to the pressure chamber for moving the piston to the ready-to-operate position. Thus, drag due to partial engagement of the clutch with the piston at the ready-to-operate position is minimized or eliminated.

摘要： A rotary fluid pump has a stator housing with a generally cylindrical cavity extending therethrough and a pair of recessed end heads assembled at opposite ends of the housing to form a pump cavity therewith. A drive shaft is journalled in the end heads by bearings and extending eccentrically into the interior of the pump cavity and a rotor is mounted on the drive shaft within the pump cavity. A pair of sealing plates of different thickness are individually disposed between the ends of the stator housing and the end heads to divide the pump cavity into a pair of end chambers defined by the end head recesses and the plates and an intermediate rotor chamber defined by the plates. A plurality of vanes are slidably disposed in an equal plurality of grooves radially formed in the rotor. The drive shaft is constrained to prevent axial displacement by stoppers, washers or a combination thereof mounted on the shaft and contacting bearings that support the shaft. The bearings are fixed to one end head.

摘要： An automatic power transmitting system for an automotive vehicle, wherein the operation of an electromagnetic clutch is automatically controlled in response to automatic shifting actions of a constant-mesh transmission by synchromesh devices. The powder clutch includes a driving rotor unit having an outer yoke and an inner yoke which cooperate to define therebetween an annular space in which a thin-walled cylindrical member of a driven rotor unit is disposed, such that the cylindrical member cooperates with at least one of the outer and inner yokes to define at least one powder gap. A small thickness of the cylindrical member assures a minimum of rotational energy consumption by the synchromesh devices. A damper may be disposed so as to connect the driven rotor unit and the input shaft of the constant-mesh transmission, so as to provide a damping effect for preventing a rapid change in an amount of torque transmitted from the driven rotor unit to the input shaft.
