Abstract (en)
[origin: EP1491769A1] The device has combined passage located upstream or downstream of a discharge chamber (32). The combined passage has restricting and a pressure restoring passages, connected in series. The pressure restoring passage is located in downstream of the restricting passage relative to flowing direction of gas. The chamber is located between a pulsation source, and the combined passage in a gas passage. The pulsation source is formed by a fixed scroll, movable scroll and sealed spaces. An independent claim is also included for a piston type compressor.
