A cylinder has at least one valve seating surface-forming portion which has an outer surface formed therein with at least one recess, the bottom surface of which serves as a valve seating surface. A discharge valve is arranged on the valve seating surface-forming portion to close or open outlet holes each formed in corresponding ones of the valve seating surface. The discharge valve has at least one valve body formed of an elastic plate member disposed in close contact with a corresponding one of the valve seating surface. Preferably, the valve seating surface is arcuately concavely curved and the corresponding valve body has a correspondingly curved surface. The outlet holes are each formed in a thinnest portion of the valve seating surface-forming portion.
