Abstract
PURPOSE: To prevent heating, seizure and the like and to ameliorate self-suction performance by a method wherein a piston is fixed to a block, a cylinder is separated from the block and the end face of a cylinder is brought by a spring into contact with internal surface of the casing to be sealed.
CONSTITUTION: The block 4 is inserted rotatively into the external peripheral surface of the eccentric part 2 of the shaft 1 supported by the casing 3 so that relative rotation can be made. A plurality of pistons 5 are arranged radially between the blocks 4 and the internal surface of the casing 3 and fixed respectively by screws to the blocks 4. Each piston 5 is inserted slidably into each cylinder 10 separated from the blocks 4 and the end surface of each cylinder 10 is energized and sealed so as to be brought into contact with the internal surface of the casing 3 by the spring 11 interposed between the block 4 and the casing. In this manner, the heating and seizure, etc. which have ever occurred for high liquid pressure in the block are not only avoided but self-suction performance can be ameliorated.
