Abstract:
An accumulator includes a pressure container, a tubular bellows, a bellows cap divisionally defining a liquid chamber and a gas chamber in cooperation with the bellows. A stay provided with a through hole partitions the liquid chamber into a closed liquid chamber on a side of the bellows and an open liquid chamber on a side of the liquid pressure port. The bellows cap includes an elastic abutment part provided with an annular sealing part positioned around the through hole to face the through hole, a buffering part is positioned on a radially inner side of the sealing part, and communication passages always communicating with the through hole are formed in the buffering part of the elastic abutment part.

Claim (Index 1):
An accumulator comprising:\n a pressure container including a liquid pressure port connected to a pressure pipe; a tubular bellows arranged telescopically along an inner wall of the pressure container; a bellows cap configured to close one end of the bellows to divisionally define, in cooperation with the bellows, a liquid chamber communicating with the liquid pressure port and a gas chamber in which a pressure gas is enclosed; and a stay provided with a through hole, the stay partitioning the liquid chamber into a closed liquid chamber on a side of the bellows and an open liquid chamber on a side of the liquid pressure port wherein: the bellows cap includes an elastic abutment part provided with an annular sealing part positioned around the through hole to face the through hole, and a buffering part positioned on a radially inner side of the sealing part; and communication passages always communicating with the through hole are formed in at least one of the buffering part of the elastic abutment part and the stay in contact with the buffering part.
