PURPOSE:To prevent discharged refrigerant from turbulence by providing a circular projection having triangular section on the top of a piston protruded into a compressed refrigerant discharging port in a valve seat plate and combining refrigerant passing by the inner and outer wall side paths respectively at the edge line of the triangular section. CONSTITUTION:The top of a projection 15a on the top of a piston protruded into a compressed refrigerant discharging port 8 in a valve seat plate 3 is formed like an edge line by the intersection of both inner and outer peripheral rising wall surfaces, i.e. a circular projection 15a having triangular section is provided on the top of the piston 15. Thus, refrigerant passing through inner and outer wall side paths a, b of the projection 15a is combined at the edge line portion on the top of triangular section, and since the respective path a, b are flared at the outlet portion, the discharged refrigerant flows smoothly without any turbulence from a discharged port 8 into a cylinder head 13. Thus, a high efficiency compressor with small discharge pressure loss is provided. |
