Abstract

PURPOSE: To minimize a leakage from a cylinder space of the high pressure side to a cylinder space of the low pressure side and improve operating efficiency by arranging a rotary cylindrical part at the end surface of a rotor and forming the former assembly as if in such manner that it is enclosed by the internal cylindrical part of a housing.
CONSTITUTION: Rotary cylindrical parts 11, 12 are arranged on the end surfaces 1c, 1d of a rotor 1 and the former assembly is formed as if in such manner that it is enclosed by the internal cylindrical parts 31a, 32a of housings 31, 32. For this reason, (a) coolant flow leaking from a cylinder spaced of the high pressure side to a cylinder space a of the low pressure side, as shown in Fig., is limited only to a region between the external diameter of a rotor cylindrical part 11, 12 and the external diameter of the rotor 1 among other rotor end surfaces 1c, 1d. Under this design, the volume of coolant leaking from the high pressure side to the low pressure side is reduced. Consequently, it is possible to efficiently discharge a coolant sucked into a cylinder space (a) from a suction port 8, into a discharge port 9 and thus carry out satisfactory operation.
