Abstract:
PURPOSE:To control the pressure of a plurality of pressure systems to the same by means of one accumulator by providing elastic bladders for housing pressure medium of the pressure systems corresponding to respective connection ports provided with valves for putting in and out the pressure medium of a plurality of the pressure systems to be controlled provided in a shell. CONSTITUTION:Bladders 2, 2' can be connected to pressure systems I , II through connection ports 7, 8 comprising respective valves V2, V3, and also connection ports 6, 7, 8, 9 comprising respective valves V1, V2, V3 and V4 are capable of opening and closing freely. Now, when pressure fluctuation such as pulsation is generated in the pressure system I , the fluctuating pressure is immediately transmitted to a pressure control medium 3 through a pressure medium 4 in the bladder 2 and is simultaneously transmitted to a pressure medium 5 and thus exerted on the pressure system II. Accordingly, the pressure system I and the pressure system II are always controlled to the same pressure and they are controlled by the pressure control medium 3 even when the pressure fluctuation is generated in any of the pressure systems.
Abstract:
Ein Druckspeicher, mit einem Speichergehäuse (2), in dem ein bewegbares Trennelement (30) einen mit einem Arbeitsgas befülIbaren Gasraum (16) von einem Fluidraum (28) fluiddicht voneinander trennt, ist dadurch gekennzeichnet, dass eine Überwachungseinrichtung (50, 54) vorgesehen ist, die bei einem die Abdichtwirkung des Trennelements (30) beeinträchtigenden Störfall eine optisch erkennbare Anzeige liefert.
Abstract:
The invention relates to a method of using new flushing ports (IA7 IB) when cleaning a piston accumulator (7). Dirty hydraulic oil is returned out via the main port (2) and a return passage (9) until a cleanness grade has been reached. Clean hydraulic oil is forced into the piston accumulator (7) via the axial bores (3A, B) of the flushing ports (IA, B) and further in sloping bores (3C, D), bringing the hydraulic oil into the volume (8) in an upward, tangential direction below the piston (5), into a flushing circulation. By reducing the gas pressure on the gas side (4) of the piston (5) in relation to flushing pressure input from a valve (6), a volume (8) is created on the oil side between the piston (5) and the end bottom (3). The return passage (9) is closed and the piston (5) is brought into its upper position, so that an internal cylinder wall (10) is cleaned. Upon pressure build-up, the return passage (9) is opened, and the piston (5) returns to its end position on the oil side while the supply of clean hydraulic oil is maintained, and the operation is repeated until a cleanness grade has been achieved.
Abstract:
Die Erfindung betrifft einen Hydraulikfluidspeicher (30) mit einer Hochdruckkammer (32) und einer Niedrigdruckkammer (33), wobei die mit einem Ausgleichsvolumen (36) versehene Hochdruckkammer (32) in der Niedrigdruckkammer (33) angeordnet ist. An dem Hydraulikfluidspeicher (30) ist ein externer Anschluss (34) für das Ausgleichsvolumen (36) vorgesehen, über welchen das Ausgleichsvolumen (36) mit einem Gas mit einem vorgebbaren Druck befüllbar ist.
Abstract:
Die Erfindung betrifft einen Hydrospeicher, insbesondere in Form eines Saugstromstabilisators, mit einem Speichergehäuse (10), das mit zwei Fluidanschlüssen (16) versehen ist, zwischen denen eine Umlenkeinrichtung (22) angeordnet ist, an die ein Gehäuseteil (26) angrenzt, das ein Trennelement aufnimmt, das das Innere (18) des Speichergehäuses (10) gegenüber einem Speichervolumen (30) abtrennt. Dadurch, dass das Trennelement aus einem Kolben (28) oder einem Balg (50) gebildet ist, lassen sich Lösungen für einen langfristigen, funktionssicheren Betrieb erhalten.
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.
