Title:
COMPRESSOR HAVING ELECTRICAL CONTROL AND HAVING A MECHANICAL ADDITIONAL VALVE
Document Type and Number:
WIPO Patent Application WO/2015/154772
Kind Code:
A3
Abstract:
The invention relates to a compressor (1) having an adjustable displacement volume, comprising a driving chamber (17), in which a driving unit, which has pistons and cylinders, is arranged, wherein the piston stroke can be changed by means of an angle-adjustable drive disk (12) and thus the displacement volume can be adjusted by means of the pressure in the driving chamber (17), the compressor having a driving-chamber feed flow, by means of which refrigerant flows via an electrically adjustable control valve (2) from the high-pressure side (outlet-pressure side) into the driving chamber (17) and with a driving-chamber outlet flow across a fluidic resistance to the low-pressure side (suction-pressure side), such that the intermediate pressure (driving-chamber pressure) in the driving chamber (17), which lies between the outlet pressure and the suction pressure, sets the adjusting angle of the drive disk (12), and wherein a mechanical valve (200) that can be adjusted by means of pressure forces is arranged in the driving-chamber feed flow, in series after the electrically adjustable control valve (2) in the flow direction.
