Starting method for a piston compressor

Abstract

The starting process for piston compressor (1) containing a piston (2) involves a returning failures creating a returning torque (AR) towards a compression point of the piston setting (S). The returning torque is held long enough for the compressor to be moved to the starting position by a fluid expelled from the compression cavity (9) through at least one leakage point (16) to overcome an inertia .to reach the starting position.

Description

technical field [0001] The invention relates to a method of starting a piston compressor. The invention still further relates to a piston compressor operated according to said method. Background technique [0002] A traditional piston compressor has at least one piston, which can be moved by a motor in the pressure cylinder in such a way that the volume of the compression space formed between the pressure cylinder and the piston can be periodically changed during the movement of the piston. expansion and compression. During the expansion stage, a compressible fluid, especially a refrigerant such as R600a, is sucked into the compression space through an inlet valve provided in the pressure cylinder. In the subsequent compression phase, the sucked fluid is compressed under increasing pressure and expelled through the outlet valve of the pressure cylinder. The piston position at which the transition from the compression phase to the subsequent expansion phase is defined as t...

Problems solved by technology

[0005] When starting a piston compressor, the momentum required for this purpose is not readily available, so often a piston compressor cannot be started with its own inherent power, or at least not from every piston position
