Abstract
Valve for a hermetic refrigeration compressor, having a cylinder block (10) with a cylinder (C) and a piston (20). A valve plate (30) attached to the cylinder block (10) has at least one axial gas passage (31, 32) communicating the inside of the cylinder (C) with the front face (30a) of the valve plate (30) through a respective reed valve at the outlet end (31b, 32b) of the respective gas passage (31, 32). The valve has a blade element (60, 80) and a biasing means (70, 90) disposed between the blade element (60, 80) and the valve plate (30) to displace said blade element to a partial opening position of the valve upon occurrence of pressure balance between the upstream and downstream regions of the valve, the biasing means (70, 90) itself being elastically deformed by the blade element (60, 80) when the valve closes, whenever the gas pressure downstream the valve exceeds the gas pressure upstream thereof.
