<p>PROBLEM TO BE SOLVED: To reduce intake pulsation at the time of a low load of a refrigerant compressor, and to prevent generation of noise without incurring increase in size of the refrigerant compressor or cost rise due to mounting of a silencer. SOLUTION: An auxiliary intake valve 40 in almost the same shape as an intake valve 30 is provided between a valve plate 2 and the intake valve 30. A throttle hole 45 with an opening area smaller than an intake port 15 is provided at the auxiliary intake valve 40. When a refrigerant flow is decreased, as only the intake valve 30 is opened, a refrigerant passing through the throttle hole 45 of the closed auxiliary valve 40 is throttled, and pulsation generated in an intake chamber 13 is reduced.</p> |
