ABSTRACT:
An acculumator having a housing and bellows located within the housing and partitioning the housing into an oil chamber and a gas chamber. A stopper is provided in the housing. The stopper has an oil passage port opposing the free end of the bellows. The free end of the bellows has a self-sealing member which opposes the oil passage port of the stopper. The self-sealing member is made of elastomer. When gas is charged into the gas chamber, the bellows expand, causing the self-sealing member to fit into the oil passage port. As a result of this, back-up oil is confined in the back-up oil chamber defined between the outer periphery of the bellows and the inner periphery of the housing. Hence, the back-up oil supports the bellows as long as the gas is being charged into the gas chamber.
