PROBLEM TO BE SOLVED: To suppress the generation of noise due to vibration generated in a discharge valve opening or closing a discharge hole for discharging compressed high-pressure refrigerant.SOLUTION: An on-off valve (discharge valve) 25 opening or closing an opening of a discharge hole 3a exposed to a notch portion 3b of a cylinder block 3 as well as a valve plate 27 that includes a valve seat hole 27a communicating the discharge hole 3a of the cylinder block 3 is attached to a valve support 29 restricting a valve opening position of the on-off valve 25 by an attachment screw 31. The valve support 29 is attached to a side block 5 (5a, 5b) by an attachment screw 33 so that the valve support 29 to which the discharge valve 25 is attached does not hold a relation of mechanical connection to the cylinder block 3. |
