Title:
COMPRESSOR
Document Type and Number:
Japanese Patent JPH02181086
Kind Code:
A
Abstract:

PURPOSE: To make the capacity changeable continuously and steplessly by providing a rear sub-plate having a bypass hole rotatably between one end plate and a rotor, and connecting both chambers with each other when both surfaces of vanes cover the bypass hole.

CONSTITUTION: If a bypass hole 59b of a sub-plate provided between a rear end plate and a rotor 15 is covered by rotation of the rotor 15 by an eccentric shaft 22, compression gas from a chamber 38 is not discharged from a discharge port 40 but bypassed to a chamber 37 instead, and if it gets apart from the bypass hole 59b, compression gas in the chamber 38 is discharged, while the other of the chamber 38 gets into a suction process, making the chamber 37 have the maximum volume. If a vane 18a covers the bypass hole 59, gas in the chamber 37 is bypassed to the chamber 38 without being compressed. The relation between the bypass holes 59a, 59b of the sub-plate and the vanes 18a, 18b is thus change by rotation of the sub-plate by a drive piston receiving the discharge pressure. Continuous stepless capacity changeable operation is thus enabled.
