PURPOSE:To reduce loss of power by providing a check valve in a path in terconnecting a compressed and enclosed space before communicating to a discharge port and a discharge chamber to send out compressed fluid to the discharge chamber when pressure in the enclosed space is higher than the discharge pressure. CONSTITUTION:An end plate 1a of a fixed scroll is provided with a discharge port 19 interconnecting a compression chamber formed of both laps 1b, 2b and a discharge chamber 16, and an outlet wall to the discharge chamber 16 is provided with a check valve 20 comprising a lead valve 20a and a valve holder 20b. Working gas is sucked through a intake hole 1c and discharged from a discharge hole 1d to the discharge chamber 16. Then the gas is discharged from a discharge pipe 11 through a motor chamber 17. When pressure in the compression chamber is higher than that in the discharge chamber 16, the check valve 20 is opened to send the gas in the comrpression chamber from the discharge port 19 to the discharge chamber 16 to prevent the compression chamber from unncessary rise of pressure. |
