Abstract
Compressor unit (12) of a compressor (10) for compressing refrigerant, comprising a drive device, particularly a drive shaft (24), for driving one or more pistons (14) that are arranged in a radial direction and that can be moved back and forth in extension and retraction movements in corresponding cylinder bores (16), wherein the drive device is in operative engagement with an eccentric (28) that controls the extension movement of the pistons (14), said eccentric (28) also controlling the retraction movement of the piston (14), the invention further relating to a corresponding compressor (10).
Claims19
A compressor unit of a compressor for compressing refrigerant, the compressor unit comprising:
- a drive device that drives one or more pistons arranged in a radial direction and configured to move back and forth in extension and retraction movements in corresponding cylinder bores, and an eccentric in operative engagement with the drive device to control the extension and the retraction movement of the pistons,
- the eccentric having an operative eccentric section with a bearing having a circular outer perimeter and in operative engagement with one or more operative connecting rod sections of respective connecting rods,
- wherein the operative connecting rod sections are arranged on the bearing by an operative connecting rod section seat, whereby the movements of the connecting rods can be disengaged from each other and wherein the operative connecting rod sections are designed to correspond with the circular outer perimeter of the bearing and are shaped as a circular segment on their side facing the bearing and have an extension that widens in an axial direction at their end facing the bearing such that they are securely arranged on the bearing in two shells designed with an L-shaped cross-section and that form the operative connecting rod section seat.
