The piston (2) is provided in the cylinder (1). The inlet seat port (4) and the outlet seat port (5) are provided on the cylinder cover (3). The inlet seat port (4) is connected with an inlet passage (6), and the outlet seat port (5) is connected with an outlet passage (7). The piston (2) carries out an up and down reciprocating motion in the cylinder (1) under the action of a power mechanism (20). An inlet valve (9) controlled by an inlet valve control mechanism (10) is provided in the inlet seat port (4). An outlet valve (11) is provided in the outlet seat port (5). When the outlet valve (11) returns to the closed state after high pressure gas is discharged, the inlet valve control mechanism (10) opens the inlet valve (9) to enable high temperature and high pressure gas in the clearance volume to return into the inlet passage (6) when the piston (2) has not left the upper dead point or just left the upper dead point a very short distance.
