Gas inlet valve for a compressor, a compressor with such a gas intake valve, as well as a method for operating a compressor with such a gas intake valve

摘要

A gas intake valve (1) for a compressor (64), comprising: a housing (2); a between a gas inlet portion (3) and a gas outlet portion (4) arranged valve means (6), wherein a valve body (57) in a closed operating state of the valve device (6) on a valve seat (56) rests in a sealing manner, and wherein the valve body (57) in an open operating state of the valve means (6) of the valve seat (56) is lifted off; a piston means (42) comprising a first piston portion (43) and a of the first piston portion (43) different second piston portion (44), wherein the first piston portion (43) in a first cylinder section (22) of the housing (2) and the second piston portion (44) in a of the first cylinder section (22) different second cylinder section (27) of the housing (2) is displaceably guided; and a in the housing (2) mounted to be displaceable piston rod (38) which the valve body (57) of the valve device (6) with the piston means (38) mechanically couples, wherein a fluid line (39) a first cylinder chamber (49) of the first cylinder section (22) with the gas outlet portion (4) operatively connecting fluid, for lifting the valve body (57) of the valve seat (56) a second cylinder chamber (52) of the second cylinder section (27) can be acted upon with a control pressure. A swing type rotary compressor as described, having such a gas intake valve (1) as well as a method for operating a compressor (64), in particular of a rotary compressor, with such a gas intake valve (1).
