Embodiment Construction

[0013] The hydraulic accumulators shown in the figures in the form of bladder accumulators serve to store a liquid or gaseous fluid medium, which can be at a pressure of up to several kilobars. The accumulator is provided at both ends with connection openings 10 for the supply and discharge of the medium, to which the individual valves are connected, which will be explained separately in more detail.

[0014] The actual pressure accumulator of the hydraulic accumulator has a first plastic housing 12 and a second plastic housing 14 which at least partially surrounds the first plastic housing 12 . The above-mentioned first plastic shell 12 is also described in technical terms as a plastic core container or as a liner, which preferably consists of polyamide and is obtained by means of a blow molding process or by sintering. The production method described above is common, so that it will not be discussed in more detail in this connection. The above-mentioned lining is reinforced...

Abstract

The gap (24) between two plastics casings (12,14) leads to a point at which the casings abut each other coaxially. A poppet valve (50) is provided in an opening (10) for controlling the supply and extraction of medium. An external support ring (22) is formed in one piece, or from at least two annular segments (28,30), at least one of which is made of plastics.

Description

technical field [0001] The invention relates to a hydraulic accumulator, in particular a bladder accumulator, for accommodating at least one fluid medium, comprising a pressure accumulator with a first plastic housing and a first The second plastic shell of the plastic shell, wherein the first plastic shell has a flange portion at least on one end thereof, the flange portion surrounds an orifice for a valve for controlling the supply and discharge of the medium, and the flange portion The second plastic housing and the second plastic housing are supported on an outer support ring located between them, which tapers wedge-like in the direction of a clearance opening between the housings. Background technique [0002] Known from EP 1248929 B1 is a plastic core container reinforced with a fiber-plastic composite as an inner plastic shell for storing liquid and / or gaseous media under pressure, wherein the core container is in the neck and / or bottom and / or Or there are one or mor...
