摘要： In a drive cam groove, a groove bottom is sloped such that a depth of the groove bottom continuously decreases from one end to the other end of the drive cam groove. The drive cam groove has: a first drive cam groove that is formed such that a distance between a center of a drive cam and the groove bottom at the first drive cam groove continuously changes from the one end toward the other end of the drive cam groove; and a second drive cam groove that is formed such that a distance between the center of the drive cam and the groove bottom at the second drive cam groove is constant from the first drive cam groove to the other end of the drive cam groove.

摘要： A spool valve includes a valve housing and a spool. The spool is slidable in an axial direction in the valve housing. A linear solenoid drives the spool against a spring. The valve housing has a feedback chamber to apply a force to the spool, an input port to receive a hydraulic pressure, an output port to produce an output pressure according to an axial position of the spool, and an drain port to exhaust oil to an outside. The spool valve has multiple supply paths to cause oil to flow from the input port to the output port and/or multiple exhaust paths to cause oil to flow from the output port to the drain port.

摘要： A coupling plate of a detent lever is assembled to an oil-pressure control device, wherein a transmission casing is a base for an assembling process. A slider of a range sensor coupled to the coupling plate is assembled to the transmission casing via a sensor body. A spool of a manual valve coupled to the coupling plate is assembled to the transmission casing via a valve body fixed to the sensor body. The coupling plate, the slider and the spool are assembled together, wherein the transmission casing is used as the base for the assembling process. It is not necessary to relatively position the slider and the spool to each other during the assembling process for an oil-pressure control device.
