PROBLEM TO BE SOLVED: To improve durability and reliability with absorption of collision noise during opening of a suction valve. SOLUTION: A valve seat member 14 having a suction opening 15 and a discharge opening 16 is provided between a cylinder head 9 and a cylinder and a head 5. The valve seat member 14 is provided with a suction valve 17 to open and close the suction opening 15 and a discharge valve 20 to open and close the discharge opening 16. Further, a valve support member 19 approximately in a U-shape is disposed between a recessed caved-in part 6 of a cylinder 5 and a mounting recess part 14A of a valve seat member 14, and the tip side of the suction valve 17 is nipped by the valve support member 19. This constitution makes the valve support member 19 to support the tip side of the suction valve 17, resulting in enabling an intermediate part 17B of the suction valve 17 to be bent for deformation and seat and off from the valve seat member 14.
