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

Hydraulic controller

A hydraulic controller comprises a first hydraulic control valve , which is mounted on an end face S of a first housing unit H , an oil pump , which is mounted on the first hydraulic control valve , and an input shaft of a transmission, which shaft is provided rotatably in a transmission housing. The oil pump comprises an outer rotor and an inner rotor in a pump casing and , which is mounted on the valve body of the first hydraulic control valve . The input shaft , which is inserted into the pump casing and fit into the inner rotor , rotates and drives the inner rotor. The oil pump sucks oil from the bottom of the transmission housing and supplies it through the mounted part into the first hydraulic control valve

Hydraulic controller for transmission

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 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.

A lubrication pressure controller comprises a lubrication pressure regulating valve,, which is provided in a lubrication oil passage,directing hydraulic oil to lubricated parts, and a cooler pressure regulating valve,, which is provided in a discharge oil passage,of the lubrication pressure regulating valve,. The lubrication pressure regulating valve,adjusts the pressure in the lubrication oil passage,, and the cooler pressure regulating valve,adjusts the pressure supplied to an oil cooler,. The hydraulic oil discharged from the cooler pressure regulating valve,is returned through a recirculation line,to a suction oil passage,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,, 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.

A driving force distributing device is provided for distributing a driving force of an engine to the left and right wheels of a vehicle by bringing a pair of hydraulic clutches into and out of their engaged states. The distributing device includes a hydraulic pump mounted within a casing thereof and driven through gears by a half shaft connected to one of the wheels. An oil passage interconnects the hydraulic pump and the hydraulic clutches, the oil passage being defined in a casing. A valve block is coupled to an upper surface of the casing. Thus, the oil passages interconnecting the hydraulic pump and the hydraulic clutches of the driving force distributing device can be compactly formed.
