    摘要： A lubrication pressure controller comprises a lubrication pressure regulating valve 41, which is provided in a lubrication oil passage 36 directing hydraulic oil to lubricated parts, and a cooler pressure regulating valve 42, which is provided in a discharge oil passage 51b of the lubrication pressure regulating valve 41. The lubrication pressure regulating valve 41 adjusts the pressure in the lubrication oil passage 36, and the cooler pressure regulating valve 42 adjusts the pressure supplied to an oil cooler 55. The hydraulic oil discharged from the cooler pressure regulating valve 42 is returned through a recirculation line 52 to a suction oil passage 31 of a pump. In this construction, an adequate supply of lubrication oil is maintained even if one of the valves experiences locking of a valve spool on an open side. Moreover, by providing signal pressure generating means 60, which applies a signal pressure to these two valves in correspondence with a driving condition, the lubrication pressure controller can be set to acquire a desired balance in the lubrication, cooling and recirculation for the hydraulic oil in response to a driving condition.

    摘要： In a stator shaft in which a shaft member is press-fitted into a press-fit bore of a flange member, first flow passages are formed in the shaft member, and blind bores extending linearly at right angles to a shaft axis from outer circumferential surfaces of the flange member and through the press-fit bore, and communication bores 103 extending linearly from a side surface of the flange member and communicating with free end portions of the blind bores are further formed. Oil passages formed of the parts of the blind bores which extend from the press-fit bore to the free end portions thereof, and communication bores constitute second flow passages, and the shaft member is press-fitted into the press-fit bore with the shaft member positioned so that the portions of the second flow passages which are opened in the press-fit bore, and first flow passages communicate with each other in a mutually opposed state, whereby the first and second flow passages are communicated with each other.

    摘要： A hydraulic controller comprises a structure composed of a separator plate 70 sandwiched between first and second valve bodies 60a and 80a, in which structure, an oil passage 103 connecting a SC shift valve 92 provided upstream and a SC backup valve 94 provided downstream is provided with a choke 75. When the separator plate 70, in which a choke opening 75a is formed, is sandwiched between the first and second valve bodies, the upstream part of the oil passage 103 is in fluid communication with one end of the choke opening 75a while the downstream part of the oil passage 103 is in fluid communication with the other end of the choke opening 75a. In this arrangement, a long narrow room formed by the choke opening 75a sandwiched between the first and second valve bodies comprises the choke 75.
