    摘要： A centrifugal hydraulic pressure cancel chamber is arranged at the back of a second piston member of a second hydraulic actuator for the second clutch. A first piston member of a first hydraulic actuator for a first clutch is situated behind the second piston. A centrifugal hydraulic pressure cancel plate is set at an inner periphery on a rotating member to prohibit axial movement and set at an outside periphery in a inside of the piston member oil-tightly. The inside surface of the second piston member and the cancel plate compose the centrifugal hydraulic pressure cancel chamber. A spring is placed between the second piston member and the cancel plate, and the centrifugal hydraulic cancel chamber and the spring work correspondingly to the first and the second piston members.

    摘要： Thrust force generated by a hydraulic actuator is absorbed in a attachment device for a four speed automatic transmission mechanism. When hydraulic pressure is applied to the hydraulic actuator to engage a third and a fourth clutches, pressing force from a piston works on a strut member situated between the third and fourth clutches as a compression force, while a force working on a drum member as a tension force, so that these forces are counterbalanced and absorbed in the attachment device. Consequently, one directional move of the attachment device is supported by a little force such as contacting a snap ring and a thrust washer to a clutch drum, on the other hand, another move of the attachment device is supported by a little force such as connecting the drum member and a big ring gear by a snap ring.

    摘要： A hydraulic control device which has a check valve controlling hydraulic pressure to a hydraulic actuator. Hydraulic pressure is selectively supplied to one of plural oil passages having different capacity orifices by a switching valve which switches high speed rotation mode and low speed rotation mode. A hydraulic power source and plural oil passages having different capacity orifices are connected to the switching valve which is controlled by hydraulic pressure varying according to vehicle speed. When rotation of the input shaft is low, the switching valve is connected to the oil passage having small capacity orifice, then hydraulic pressure is supplied to the hydraulic actuator through the orifice of small capacity. At this stage, as centrifugal force working on the ball in the check valve is low, the check valve is closed by even small amount of oil supply through the small capacity orifice, and raises hydraulic pressure in the actuator, so the clutch is engaged smoothly. When rotation of the input shaft is high, the switching valve is connected to the oil passage having the large capacity orifice, then hydraulic pressure is supplied to the hydraulic actuator through the large capacity orifice. At this stage, even if centrifugal force works on the ball is large, the check valve is closed by large amount of oil supply through the large capacity orifice, and raises hydraulic pressure in the hydraulic actuator, so the clutch is engaged smoothly.

A tightly sealed space in communication with an oil pump is provided in the lower part of the transaxle housing, formed in such a manner that it can be opened by the removal of a cover member which is secured to the transaxle casing in a freely mountable and removable manner. An oil strainer is housed in the tightly sealed space and an intake adapter is provided in communication with the tightly space and an oil sump. As a result the oil in the oil sump is taken into the intake opening of the oil strainer from the adapter, and foreign matter such as iron particles and the like is removed in a filter element and the filtered oil is supplied to an oil pump.

    摘要： Seal rings are set in oil grooves which are situated at both sides of two oil passages communicating two hydraulic actuators which operate oppositely. First and second seal rings oil-tightly seal between the first oil passage and sleeve, while third and fourth seal rings oil-tightly seal between the second oil passage and the sleeve. Accordingly even if oil flows oppositely in each of two oil passages due to the opposing motions of the two contiguous hydraulic actuators, not oil leakage occurs. Furthermore, a draining groove is situated between the oil grooves in which the second and third seal rings are installed.
