Abstract: An hydraulic pressure reservoir having at least one pressure chamber with a fluid connection to a hydraulic circuit. The pressure chamber is formed between a movable partition member carried in a housing and having a pressure limiting valve, and a fixed partition. The movable partition member is in the form of a diaphragm spring.

Abstract: In a metal bellows accumulator, a metallic bellows unit is disposed within a pressure space defined in a main shell, and one end of the metallic bellows unit is fixedly secured to one end wall of the main shell. The metallic bellows unit sections the pressure space into an outer chamber serving as a gas chamber in which a pressurized gas is enclosed, and an inner chamber serving as a liquid chamber communicating with a liquid port formed in the end wall of the main shell. A stopper (auxiliary shell) for limiting collapsing movement of the metallic bellows unit is disposed within the liquid chamber and has a communication passage hole. The liquid port always communicates with a liquid chamber to which an inner circumferential surface of a bellows portion of the metallic bellows unit is exposed via the communication passage hole.

Abstract: 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.

Abstract: A means for mounting a diaphragm in an accumulator-reservoir device or the like in which the gland receiving the diaphgram bead has faces formed to oppose such pull on the bead as will break the sealing contact between gland faces and the bead. Back draft angles and grooved surfaces are used in conjunction with an initial applied compression to fix the bead in place in the gland.

Abstract: A pressure transfer unit having a movable partition including a flexible bellows for separating an internal, controlled-pressure chamber from a reference-pressure chamber. A valve is provided for limiting the volume of liquid that can be injected into and received in the controlled-pressure chamber during filling or refilling thereof. A spring biases the partition to apply a predetermined force to the partition and to shut off fluid transfer in the event of bellows failure. The unit is arranged for simple and rapid assembly and disassembly.
