Abstract

PURPOSE: To make the input horsepower variable within various ranges by introducing the pressure produced by a pump itself to a first port; and at the same time by providing a second port for introducing another pressure.
CONSTITUTION: A chamber 13a is inserted into a block 13 fixed to the lower side of a body proper 1, and a piston 14 is mounted in the chamber, and the tip of the rod 14' of the piston is made to compress the PC spring 12 supported between spring supporters 18 and 19. A spring supporter 15 simultaneously with one 16 are provided within a cover 17 fixed to the block 13, and the spring supporter 51 is made to touch the head of the piston 14. The first port P is linked with the exhaust and suction pressure from a pump A to be controlled, while the second port Q is linked with a pressure pipe line from the other pressure source. An inclined angle α is to be reduced in the direction of an arrow in the case of a pump, and it is to be increased in the same direction as to a motor. Therefore, it is possible to change the input horsepower of a pump or motor to various ranges.
