PURPOSE: To easily and accurately form a fixed throttle in a passage, intercommunicating a crank chamber, an intake chamber, and a delivery chamber, so that a throttle amount is adjusted to a given value. CONSTITUTION: A rear housing 4 is securely joined with the rear end face of a cylinder block 1 through a valve plate 3 and a gasket 29. A fixed throttle 51 is located in the middle of an air bleeding passage 31 to intercommunicate an intake chamber 11 and a crank chamber 17. The fixed throttle 51 is formed in such a way that a communicating groove 51 having a given width is notched in the gasket 29.
