圧縮機
Document Type and Number:
Japanese Patent JP4454318
Kind Code:
B2
Abstract:
A compressor is disclosed. It comprises a compression element having a cylinder defining a compression space therein and suction and discharge ports in communication with said compression space, a cylindrical compression member having a lower end surface, a peripheral side surface and, an upper end surface facing the compression space disposed in the cylinder to compress fluids sucked into the compression space through the suction port and discharge them through the discharge port in response to rotation of the compression member about its longitudinal axis and, a vane disposed in the cylinder between the suction and discharge ports which contacts and follows the upper surface of the compression member to partition the cylinder into low and high pressure chambers. The upper end surface of the compression member is in the form of a continuous curve configured so that fluid entering the low pressure chamber via the suction port is compressed by the compression member as the compression member rotates. A piston ring is disposed in the compression member to seal a clearance space between the peripheral side surface of the compression member and the cylinder.
