摘要： In the interior of the housing of an accumulator, a metallic bellows and a self-seal mechanism are arranged. The metallic bellows partitions the interior of the housing into a gas chamber and a liquid chamber. The self-seal mechanism includes an elastic seal member and a face which the elastic seal member opposes. When the bellows is compressed to the predetermined extent due to introduction of a compressed gas into the gas chamber, the elastic seal member is brought into contact with the face, thus closing a flow port. The elastic seal member has a slanted face, so that a wedge-shaped liquid guide gap is produced when the elastic seal member is in contact with the face. When, in this condition, the compressed liquid is introduced into the flow port, part of the liquid enters the liquid guide gap, thus permitting the seal member to easily separate from the face.

摘要： A coated coil spring wrapped in a coating member prepared from a soft synthetic resin foam, wherein the coating members of the respective coil spring turns constituting at least the effective region of the coil spring are provided with a helical clearance; and the width of said clearance accounts for 0.15 to 0.50 times the width of the adjacent coil spring turns.
