Abstract: A hydropneumatic assembly particularly for use as a pressure reservoir in a shock absorber includes a housing with a diaphragm operatively mounted within the housing to define therein a liquid chamber on one side of the diaphragm and a gas chamber on the opposite side thereof. The liquid chamber is defined between an inner wall of the housing and the diaphragm and the diaphragm is arranged to be pressed against the inner wall under the influence of gas pressure within the gas chamber. Damping liquid for a shock absorber flows into and out of the liquid chamber to an opening provided in the inner wall of the housing and, by a special feature of the assembly, ducts are defined between the inner wall of the housing and the diaphragm, with the ducts being directed to extend toward the opening through which liquid flows into and out of the liquid chamber.
