Abstract (en)
A piston-type compressor includes a crank chamber (15), a drive shaft (16), cylinder bores (33), and a valve plate (14). The drive shaft (16) passes through the crank chamber (15), and the valve plate is fixed to the rear of the cylinder bores (33). The drive shaft (16) includes a valve body (47). The rear end surface (47a) of the valve body (47) and the front surface of the valve plate (14) form a valve mechanism (46). The valve mechanism (46) is located in the pressurizing passage (18, 12a, 44). The valve mechanism (46) adjusts the opening size of the pressurizing passage (18, 12a, 44) in accordance with the axial movement of the drive shaft (16) from a reference position. This maintains an appropriate relationship between the pressure in the cylinder bores (33) and the pressure in the crank chamber (15). <IMAGE>
