Abstract

PURPOSE: To improve the bulk efficiency of a cooling medium compressor with the top clearance reduced by providing a discharge valve with a projection.
CONSTITUTION: A discharge valve 9 is provided with a projection extending into a discharge port 13 to reduce the volume of the discharge port 13. With this arrangement, in which the projection 14 of the discharge valve of the cooling medium compressor extends into the discharge hole 13, the top clearance can be widely reduced. In addition, the projection 14 also serves the role of a guide member for gradually varying the direction of flow of the cooling medium gas through the discharge port 13, so that it is possible to the bending loss as well and widely improve the bulk efficiency of the cooling medium compressor.
