Abstract

PURPOSE:To reduce energy loss by furnishing a pair of cylinder parts and a pair of piston parts inserted into each cylinder part and providing a discharge port in one piston part. CONSTITUTION:The piston parts 7, 8 are reciprocated by the action of a driving part 9. When the piston part 7 is moved to one side, the gas S2 in a suction part 2 is sucked into the cylinder part 5 from a through-hole 3 by the action of nonreturn valves 11, 12. When the piston part 7 is moved to the other side, the gas S2 in the cylinder 5 is discharged into water S1 through the discharge port 10. Consequently, the discharge of the gas S2 is repeated through the discharge port 10 by the reciprocating motion of the piston part 7. By this mothod, the gas is sent out with minimum power and energy is saved.

Further, a swinging rod 26 extending from the piston rod 24 is provided from the outer end surface 8a of the piston portion 8, and is connected to a driving rod 9 including a crank mechanism 27, a motor portion 28, and the like. Therefore, the piston rod 24 is caused to reciprocate by the drive section 9. The drive section 9 is housed in a case 29 which is an extension of the cylinder section 6, and an opening 30 is provided so that the outer end surface 8a of the piston section 8 is exposed to the water SI. Further, the piston portion 7 is provided with a discharge hole 1O, and is also provided with a check valve 11 that prevents inflow into the cylinder portion 5 from the outside.

It flows into the cylinder part 6 through the through hole 4 as shown in FIG. Also, since the check valve 12 is closed and the check valve 1l is opened, the gas S2 stored inside the piston part 7 is released from the discharge hole 10 to the outside as indicated by the arrow H2, and is stored in the gas storage part 35. be done.
