    摘要: A variable capacity pump and two variable capacity motors are connected in a closed circuit. First to fourth drive gears are fitted to motor shafts of the variable capacity motors via clutches. A first driven gear, which meshes with the first and third drive gears, and a second driven gear which meshes with the second and fourth drive gears are fitted to an output shaft. Equivalent capacities of the variable capacity motors are made different. Control is exerted such that the capacities are decreased to zero in order of equivalent capacities. To decrease the capacity of each variable capacity motor, the gear change ratio of the variable capacity motor the capacity of which has decreased to zero is changed to decrease the equivalent capacity and, at the same time, the capacity is increased to maximum. This increases the gear change ratio for the continuously variable transmission and controls acceleration.

    摘要: It is designed that an oil pressure signal can be output by operating an operation lever in a twisting direction; a structure can be made simple and its assembly and adjustment are easy; an operation force can be reduced; and a layout is not restricted. It is also designed that when the operation lever is left free after it is twisted, it returns smoothly to the original neutral position. When the operation lever is twisted about the lever axis, the shaft supported by bearings is twisted. The twist of the shaft is converted into the movement in a direction to move the pistons by first and second levers, and the pistons are moved. When the pistons are moved, the oil pressure signal is output from the discharge ports. A disk plate is separated into a first disk plate to which the root of the operation lever is attached and a second disk plate which is tiltably supported by a tilting fulcrum. And, the first disk plate is independent of the second disk plate and twisted about the lever axis of the operation lever.

    摘要: A pressure compensation valve comprises a check valve portion having an inlet port that is connected to a discharge path of a hydraulic pump, an outlet port that is connected to an inlet side of a directional control valve, and a valve for controlling an area of opening between both ports. A pressure reduction valve portion has a spool that defines at its both sides a first pressure chamber and a second pressure chamber, respectively, and is adapted to be slidable to allow the valve to be thrusted in a first direction in which the area of opening is increased under a self-load pressure applied to the first pressure chamber and to be slidable to allow the valve to be thrusted in a second direction in which the area of opening is decreased under a pressure within the second pressure chamber. An internal passage is formed inside of the spool and is adapted to supply a discharge pressure fluid of the hydraulic pump to the second pressure chamber when the spool has been slid to assume not less than a predetermined displacement made in the first direction.
