Method for the production of a bladder accumulator and bladder accumulator produced according to said method

The invention relates to a method for the production of a bladder accumulator (10) which separates two media chambers (16, 18) from one another in a storage housing (12) by means of a bladder body (14), comprising at least the following production steps:—extruding a plastic tube over the bladder body (14);—shaping the plastic tube with the integrated bladder body (14) in a molding tool that corresponds to a predeterminable plastic core container (20), and—winding at least one plastic fiber from the outside on the plastic core container (20) for the purpose of creating the storage housing (12).. . ...

Method for producing a foam body

A method for producing a foam body, in particular for a pressure accumulator, such as a hydraulic accumulator, the bubble- or diaphragm-shaped, elastically flexible separating layer (12) of which separates two media chambers from each other within the accumulator housing, in particular a gas working chamber from a liquid chamber (18), with at least the following production method steps: —introducing a flowable, preferably liquid, foam material into the pressure accumulator, said foam material being at least partially surrounded by the separating layer (12), —curing the foam material in the pressure accumulator, and in the process—building up a pressure gradient, in which the visibly curing foam material expands the separating layer (12) from an originally partially filled starting state in the direction of an end state, in which the accumulator is finally filled with the cured foam (38).. . ...

Hydropneumatic pressure accumulator

The invention relates to a hydropneumatic pressure accumulator, in particular a pulsation damper, comprising an accumulator housing (2) and a movable separating element (20), which separates a pressurized working gas-containing gas working space (24) from a fluid chamber (22) in the accumulator housing (2). The hydropneumatic pressure accumulator is characterized in that a gas storage chamber (12) is provided, which contains an additional volume of the pressurized working gas, said gas storage chamber (24) being connected via a connecting path (30) having a throttle point.. ... Hydac Technology Gmbh

Method for manufacturing a pressure vessel

A method for manufacturing a pressure vessel (2), which is preferably provided for use in bladder accumulators, comprising the following manufacturing steps:—providing a support structure (22), more particularly in the form of a liner;—applying a fibrous material (24) to the support structure (22) to form a base structure (20);—placing the base structure (20) in a heatable mold apparatus (4, 6, 10); and—introducing a matrix between the mold apparatus (4, 6, 10) and the base structure (20), which partially penetrates the fibrous material (24).. . ... Hydac Technology Gmbh

Connecting apparatus

The invention relates to a connecting apparatus, provided for fluid-conducting connection to at least one main component (10), which component has a plurality of mutually adjacent fluid passage points (p′1, p′2, p′3, p′n . . ... Hydac Technology Gmbh

Filter device and filter element for such a device

A filter device together with a filter element for such a device. A filter device having a securing device (10) for securely fixing a filter element (12) on an element mount (14) is characterized in that the securing device (10) includes a securing means (16), which may be moved by means of a control device (18) from a position in which the filter element (12) on the element mount (14) is released into a position in which the filter element (12) is fixed on the element mount (14).. ...
