TH47280A - Volute compressors with pressure chambers opposite the discharge chamber. - Google Patents

Abstract

DC60 (05/03/44) The teeth of the fixed spiral slices (2a) protrude from the tip plate (2b) of the pinned spiral slices (2) and the teeth of the fixed spiral slices (2a). Volute (4a) extends from the end plate (4b) of the movable spiral (4) the tip (4b) of the spiral. Movable (4) channels (8) for releasing gas Refrigerated compressed There is a pressure chamber (16) at the back surface of the end plate (2b), there is an opening (10) that contacts the pressure chamber (16) at the location of the end plate (2b) opposite to the discharge port (8). What has been A spiral compressor that reduces ripple when the fluid is released. By feeding the compressed fluid into the pressure chamber, the tooth of the fixed spiral (2a) extends from the tip (2b) of the fixed spiral (2) and the tooth of the fixed spiral (2). Volute (4a) extends from the end plate (4b) of the movable spiral (4) the tip (4b) of the spiral. Movable (4) channels (8) for releasing gas Refrigerated compressed There is a pressure chamber (16) at the back surface of the end plate (2b), there is an opening (10) that contacts the pressure chamber (16) at the location of the end plate (2b) opposite to the discharge port (8). What has been Clam-type compressors that reduce ripple when the fluid is released. By feeding the compressed fluid into the pressure chamber

Claims (7)

1. The spiral compressor consists of The first spiral body with the first spiral body extending from the end plate. A second spiral body with a second spiral body extending from the end plate to articulate. With a bottom body One such shell. And cause a compression chamber The discharge port is arranged on the said end plate of the spiral. The first and two of the above The discharge port contacts the pass provided in the drive shaft to drive the first spiral. Or that second spiral piece The pressure chambers are located on the back surfaces of the remaining one and two of the spirals, and the opening is placed on the end plate of the remaining one. To contact such pressure chambers Where the opening is positioned opposite to the said release. And where the opening goes straight through the end plate of the other spiral left in the direction that Cast out of the drive shaft 2. The spiral compressor of claim 1, in which the pressure chamber is formed by another remaining part of the said spiral and the lid. 3. The spiral compressor of claim 1, in which the first spiral piece is a fixed spiral piece. The second spiral is a movable spiral and the opening is located on top of the fixed spiral. 4. The spiral compressor of claim 1, in which the opening is positioned at It is said to be opposite to the said outlet in order to prevent the drive shaft vibration. 5. The spiral compressor of claim 1, in which the opening is positioned at Classified as opposed to the said discharge hole In order to suppress the pulsation of the emitted gas 6. The spiral compressor of claim 1 also includes an adjustment chamber. A pressure relief is placed on one such end plate of the remaining volute for carrying the compression process fluid to the pressure chamber. And a pressure relief valve that opens / closes the channel Adjust the pressure relief. 7. The volute compressor of claim 6, which the pressure relief valve It consists of a one-way pressure relief valve for opening and closing the vent. The pressure in response to the excess pressure in the compression chamber.
