    摘要： A thin walled membrane type diaphragm particularly for liquid pressure accumulators and a method of production is disclosed comprising membrane made from rubber, synthetic rubber, P.V.C. or like suitable material including a neck portion forming the opening of the diaphragm and adapted to be mounted in the neck of a pressure tank and a closed tank region or body region which is formed from cruciform pleats which may be symmetrical such that the dimension of the body portion is reduced for a given volume of body region.The moulding of the diaphragm in this form enables a diaphragm of greater internal capacity to be moulded in a given sized injection moulding such that the core size of the moulding machine can be readily removed through the base region of the diaphragm.

    摘要： An elastic separating wall to be arranged between a gas chamber with a high pressure and a liquid chamber, particularly for a pressure accumulator, comprises an elastic separating wall member composed of a plurality of layers, the layers including at least two outer layers, and at least one inner layer composed of a material having a high gas permeability, means for connecting the elastic separating wall member to a wall of a container in a connecting region, and a passage arranged in the region and communicating with the inner layer with an atmosphere.
