ABSTRACT:
A rod is inserted in a first cylinder. A first oil chamber is defined by the inner surface of the first cylinder. The rod can be reciprocated with a first stroke. A second cylinder is coupled to the first cylinder by a connecting member. A metal bellows is housed in the second cylinder. A gas chamber is defined by the inner surface of the bellows. A second oil chamber is defined by the outer surface of the bellows and the inner surface of the second cylinder. The bellows contracts with a second stroke corresponding to the first stroke of the rod. The first and second oil chambers communicate with each other via an oil path formed in the connecting member. A valve seat is arranged on an end wall of the second cylinder. A valve body is fixed to the bellows so as to oppose the valve seat. If the bellows expands farther than the second stroke when a gas is supplied into the gas chamber, the valve body is brought into contact with the valve seat. When the valve body and the valve seat are brought into contact with each other, the oil is entrapped in a gap between the inner surface of the second cylinder and the outer surface of the bellows body.
