    Abstract: 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.
