摘要： A spool is constituted by an outer spool 60 for opening and closing ports 52, 54, 56 provided in a sleeve 50 and an inner spool 70 that is contacted by a shaft 38 of a solenoid portion 30 and opens and closes a feedback chamber 58. A spring 80, which is interposed between the outer spool 60 and the inner spool 70, is designed to be capable of receiving precisely a total load of a load applied to the outer spool 60 by a feedback force generated when an output pressure reaches a predetermined pressure P1 and a load applied to the outer spool 60 by a biasing force of a spring 44. Therefore, by pushing the inner spool 70 using the solenoid portion 30 such that the outer spool 60 is moved in an axial direction via the spring 80, the respective ports 52, 54, 56 can be opened and closed, and the feedback chamber 58 can be opened from a closed state by the biasing force of the spring 80.

摘要： A pressure control valve includes a sleeve on which an input port, an output port, and drain ports are formed; and a linear solenoid portion for generating thrust. The pressure control valve further includes a first spool, which advances and retreats within the sleeve, for receiving the thrust, regulating input pressure input to the input port, and outputting the regulated output pressure from the output port; and a second spool, which advances and retreats within the sleeve, for receiving the thrust, and selectively applying output pressure to the first spool. The output pressure is selectively applied to the first spool, thereby doing away with the need for a control valve or the like. This simplifies the oil pressure circuit for generating control pressure, and allows control pressure to be generated in a stable manner, and the size of the pressure control valve to be reduced.

摘要： The present invention prevents foreign matter from infiltrating into a control valve and enables reduction in the cost of the valve. A strainer is mounted on an attachment portion of a valve sleeve, and a valve spool is disposed in the sleeve so as to be free to slidably advance and retreat. The strainer includes engagement portions m1 contacting first contact sites ε1 and ε2 formed on the attachment portion and a contact portion contacting second contact sites ε3 and ε4 formed on the attachment portion. Since the strainer includes the engagement portions m1 in contact with the first contact sites ε1 and ε2 and the contact portion in contact with the second contact sites ε3 and ε4, the sleeve has sufficient sealing contact with the strainer 73 at the first and second contact sites ε1 to ε4.

摘要： A power transmission device that transmits power from a motor to a wheel via a hydraulically driven friction engagement element and that includes a mechanical pump driven by the motor to produce a hydraulic pressure that is regulated by a pressure regulating valve; an electric pump that produces a hydraulic pressure; a switching mechanism that either switches an output pressure of the regulating valve or an output pressure of the electric pump to a servo of the engagement element based upon a signal pressure; a passage to supply pressure from the mechanical pump to the hydraulic servo; a check valve in the passage that allows supply of the pressure from the mechanical pump to the hydraulic servo and prohibits supply of the pressure from the electric pump to the mechanical pump, and the switching mechanism either shuts off or allows communication through the passage based upon the signal pressure.

摘要： An automatic transmission including an input shaft connected to a drive source; an output shaft connected to a driving wheel; a one-way clutch; friction engagement elements which establish speeds by changing a transmission path between the input shaft and the output shaft based on the application state of the friction engagement elements and application of the one-way clutch, one of the friction engagement elements being a brake that is applied when coasting in a take-off speed. The automatic transmission also includes a controller that determines whether it is possible to initially establish the take-off speed using the one-way clutch based on a predetermined condition, and, if not possible, then the controller establishes the take-off speed by applying the brake.
