Abstract

PURPOSE: To prevent leakage of liquid form the spaces formed between the side faces of gears and wall surfaces of blocks, by bringing sheet members into close contact with the side faces of the gears by means of resilient members.
CONSTITUTION: Liquid supplied from a suction space 1a' is carried to a discharge space 1a" through a space formed between turning gears 2, 3 and forced out by a pair of engaged gears. Then, it is discharged to a liquid outlet port 11 through the discharge space. Sheet members 20, 21 are urged into close contact with the side faces of the gears 2, 3 by means of resilient members 26, so that outflow and back flow of fluid from the spaces between the side faces of the gears 2, 3 and wall surfaces of blocks 1a, 1b can be prevented, and at the same time, load due to friction between the gears 2, 3 and sheet members 20, 21 can be lowered. Therfore, it is enabled to prevent leakage of fluid.
