摘要： It is intended to provide a swash plate type continuously variable transmission capable of automatically affording a lock-up state in which second distributing valves are stopped at their stroke mid-point to cut off motor ports when a motor swash plate stands upright, even without using any special interlocking mechanism. Second distributing valves for bringing motor ports of motor cylinder bores into communication with a high-pressure oil path and a low-pressure oil path selectively in an alternate manner are arranged in parallel with the axis X of a cylinder block; a valve swash plate for reciprocating the second distributing valves is integrally combined with a motor swash plate on the same slant plane; and the motor ports are formed so as to be controlled selectively by the second distributing valves at respective positions 90.degree. out of phase in the circumferential direction of the cylinder block 4 with respect to the corresponding motor cylinder bores, the second distributing valves being stopped at their stroke mid-points when the motor swash plate stands upright. In a swash plate type hydraulic unit for use as a swash plate type oil-hydraulic pump or motor, it is intended to attain the reduction in radial size of the hydraulic unit while ensuring a sufficient plunger stroke.

摘要： A pump and motor distribution valve formed by a hydraulic closed circuit for connection between a pump and a motor. In a hydraulic non-stage transmission CVT including a swash plate plunger type hydraulic pump P and a swash plate plunger type hydraulic motor M connected to each other through a hydraulic closed circuit, a pump swash plate member is driven to rotate. A pump cylinder and a motor cylinder are connected to each other and disposed in a connected state on an output shaft. A motor swash plate, restricted in rotation, is oscillated, and the swash plate angle can be regulated variably. A pump-side spool rotatable as one body with the pump swash plate member and a motor-side spool maintained fixedly are inserted in a valve hole formed in the output shaft to penetrate through the output shaft in the axial direction. A hydraulic closed circuit includes the spools and a plurality of communication oil passages formed in the pump cylinder, the motor cylinder and the output shaft.
