Abstract:
The pressure vessel (1) for liquid comprises a body (10) containing a substantially non-elastic membrane (22) which divides the body into a liquid chamber (16) for receiving liquid under pressure from a source and a gas chamber (20) for containing gas. The membrane (22) is movable by the liquid under pressure entering the liquid chamber (16) so as to compress the gas. An outlet (24) is provided from the liquid chamber (16) through which the liquid therein can be driven by pressure in the gas chamber (20) acting against the membrane (22). The pressure vessel (1) is particularly useful for flushing a toilet receptacle (35) or (47). The toilet receptacle (47) is provided with a device (48) which can be extended into the toilet receptacle (47) to deliver water for flushing the toilet receptacle or for enabling the toilet receptacle to be used as a bidet.

Abstract:
Es wird ein Druckmittelspeicher mit einem Gehäuse (1) vorgeschlagen, dessen Innenraum durch ein Medientrennung-selement (2) in zwei Kammern (3,4) unterteilt ist, wobei die erste Kammer (3) mit einem Gas und die zweite Kammer (4) mit einer Flüssigkeit gefüllt ist und wobei in einem hydraulischen Anschluß (5) ein Bodenventil (6) vorgesehen ist, das ein Befüllen der zweiten Kammer (4) mit Flüssigkeit ermöglicht und ein vollständiges Entleeren der zweiten Kammer (4) verhindert, dessen Schließkörper (7) durch das Medientrennungselement (2) betätigbar ist. Um insbesondere bei niedrigen Temperaturen und hoher Viskosität des Druckmittels eine Beschädigung des Medientrennungselementes durch einen für den Füllvorgang erforderlichen hoher Differenzdruck bzw. eine daraus resultierende hohe hydraulische Kraft zu verhindern und somit eine erhebliche Erhöhung der Funktionssicherheit zu gewährleisten wird erfindungsgemäß vorgesehen, daß zwischen dem Medientrennungselement (2) und dem Bodenventil (6) Mittel (26,81,82) zur Reduzierung der vom Schließkörper (7) des Bodenventils (6) auf das Medientrennungselement (2) übertragbaren Kraft vorgesehen sind.
Abstract:
The invention relates to a hydropneumatic pressure reservoir device comprising a reservoir housing (10) with a membrane (12) therein, forming a moving separating element between a first chamber, in particular a gas chamber (14) and a second chamber, in particular a fluid chamber (16). In a fluid-free state of the fluid chamber (16) said membrane covers an inlet opening (18) in the reservoir housing (10) with a closing piece (20) and is fixed within the reservoir housing (10) at the free fixing edge (24) thereof, by means of a fixing device (26). A very flat construction of hydro-reservoir is achieved, which provides a reliable isolation of machine components by application of said hydro-reservoir, whereby the reservoir housing (10) has a flat support surface (36) running along the side thereof facing a fixing point (34) and a spring elastic support piece (40) runs between the support surface (36) and the fixing point (34), to produce the connection between reservoir housing (10) and fixing point (34).
Abstract:
The invention relates to a hydraulic accumulator, especially a piston accumulator, comprising an accumulator housing (10) and at least one gas chamber (12) and a fluid chamber (14), these being separated from each other by a separating element (16). At least one of these chambers (12, 14) can be filled with a pressure medium or at least partially emptied of the same through at least one valve control unit (26) which has a switching valve (28, 30). The respective switching valve (28) is accommodated in a corresponding valve location (29), and can be moved in the direction of movement of the separating element (16) from an opening position into closing position and vice-versa. The aim of the invention is to avoid an expensive line network between the hydraulic accumulator and the valve control unit, so that sealing or leakage problems such as are common in a line network, never occur, To this end, the valve control unit (26) is accommodated in a valve block (24) which is independent from the housing (10), said valve block (24) has an additional valve location (31) for an additional switching valve (30) for performing another switching task, and the valve locations (29, 31) are configured essentially identically and are situated eccentrically in relation to the longitudinal axis (33) of the hydraulic accumulator for modular use of the switching valves (28, 30), which are configured as identical parts.
Abstract:
The invention relates to a hydroaccumulator, in particular a bladder accumulator. Said accumulator comprises a pressurised container (1), a separation element (5) which is located in said container and separates a gas chamber (7) in the pressurised container (1), lying adjacent to an inlet on the gas side from a fluid chamber (9), lying adjacent to an inlet on the fluid side (3), said inlet having a fluid connecting sleeve (11) and a valve arrangement located on the connecting sleeve (11), said arrangement having at least one valve body (17) that has a transversal bore (33). The valve body is usually pretensioned in an open position which allows the passage of fluid and can be displaced into a closed position by a displacement of the separation element (5), the interior surface (15) of the connecting sleeve (11), which lies directly against the valve body (17), guiding the displacement of said body between the open and closed positions. As the side of the valve body (17') that faces the separation element (5) is configured as a plate running on one plane, as the respective transversal bore (33), which is delimited by the plate (17') in the open position, opens at least partially into the fluid chamber (9) and as the diameter of the valve body (17) is greater than its height, measured in the direction of displacement of said valve body (17), the valve arrangement has a plate-valve construction of small proportions and can be cost-effectively produced.
Abstract:
The invention relates to a hydraulic fluid accumulator comprising a housing (1), whose interior is subdivided into three chambers (2, 3, 4), whereby the first chamber (2) is filled with a gas and separated from the second chamber (3) by a first media separation element (6). Said second chamber is filled with a liquid and is separated from the third chamber (4), which is also filled with a liquid and is connected to a hydraulic line (5), by a second media separation element (7). To guarantee an effective separation of the media within the hydraulic fluid accumulator and thus a significant increase in its functional safety, the invention is characterized in that the second media separation element (7) is embodied by a metal piston (8, 80) which delimits a space that can be deaerated (9, 90) in the housing (1).
Abstract:
The invention relates to a method for measuring the gas pressure in gas suspension or gas storage spheres (1), in particular, when in the assembled state in a motor vehicle and a device for application of the method. According to the invention, the checking of gas suspension or gas storage spheres my be simplified, whereby, for determination of the gas pressure, at least one temperature measurement of the shell of the sphere is taken, the actual value determined is compared with a set value thereof and the resulting difference is displayed. By means of the temperature measurement taken of the shell of the sphere, with reference to the stored measured data for the various operating states of the gas suspension or gas storage spheres (1), deviations from the set values may be determined in a simple and reproducible manner. The particular advantage of the invention is that the measurement may occur in the constructed vehicle and only the hydraulic pressure in the vehicle need be altered.
