Title:
VARIABLE CAPACITY COMPRESSOR
Document Type and Number:
Japanese Patent JPS61218783
Kind Code:
A
Abstract:

PURPOSE: To try to miniaturize the compressor in the caption by engaging one of through bolts with one corner of a shaking board through a universal joint fitted with the bolt so as to achieve smooth travelling of the shaking board and prevent it from revolving as well as to make a conventional guide pin unused and remove an extended part from the jointed body.

CONSTITUTION: A ball guide 22 makes sliding motion on a through bolt 21a, following the travelling of a shaking board 13. On the other hand, while guide shoes 23, 23 pinching the ball guide 22 make smooth sliding motion with respect to the ball guide 22 on their concave hemispherical surfaces 23a, 23a, their rear surfaces 23b, 23b formed in a convex shape make smooth sliding motion relatively along an opposing surfaces 13b, 13b of an opposing slot. Therefore, smooth travelling of the shaking board 13 and preventing it from revolving can be achieved. Since a guide pin for preventing the shaking board 13 from revolving does not have to be provided and no extended part is made on a jointed body including a cylinder block 1, it is attempted to reduce the number of parts as well as to miniaturize the compressor.
