Title:
COOLANT COMPRESSOR
Document Type and Number:
Japanese Patent JPH09287583
Kind Code:
A
Abstract:
To reduce manufacturing cost while dispensing with a guide cylinder of a suction valve, and improve sealability of the suction valve, when closed thereof, without complicated processes.
A valve housing chamber 34 is formed on the way between a suction port 6a and a suction chamber 11, while a coil spring 33 is directly housed in the valve housing chamber 34 without a guide cylinder. Since the guide cylinder is not used, a lower end face of a bush 31 is not affected, which may be deformed otherwise due to welding between the guide cylinder and the bush 32. It is thus unnecessary to process the lower end surface of the bush 31 afterward for obtaining the flatness.
