Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/011769
Kind Code:
A3
Abstract:
The invention relates to a scroll compressor which comprises the following: a compressor unit (20) having a stationary stator spiral element (21) and a rotatable rotor spiral element (22) which is mounted so as to be axially movable relative to the stator spiral element (21), wherein the compressor unit (20) is designed to suction and compress a fluid to be compressed from a suction region (30) and to convey it into a high-pressure region (40); a counter-pressure chamber (10) which is arranged on a side of the rotor spiral element (22) facing away from the stator spiral element (21) and which can be subjected to a counter-pressure in order to exert a pressing force on the rotor spiral element (22) in the axial direction and to press the rotor spiral element (22) against the stator spiral element (21); wherein a fluid connection exists between the counter-pressure chamber (10) and the suction region (30), and wherein a fluid connection exists between the counter-pressure chamber (10) and the high-pressure region (40); a suction pressure channel (103) which is arranged in the fluid connection between the counter-pressure chamber (10) and the suction region (30); a high-pressure channel (104) which is arranged in the fluid connection between the counter-pressure chamber (10) and the high-pressure region (40); wherein at least one actuator element (101, 102, 101a) is arranged in the high-pressure channel (104) and the suction-pressure channel (103), by means of which the cross-section of the high-pressure channel (102) and of the suction pressure channel (103) can be changed.
