摘要： A hydraulic accumulator (14) is equipped with a novel shut-off valve. The shut off-valve includes a valve body (21) having a cylindrical hollow with a valve seat (37) surrounding one end. The main piston (24) including a piston head has a central opening (30) and is slidably mounted within the cylindrical hollow of the valve body. A poppet valve (22) has a valve head which mates with the valve seat and a valve stem which extends through the central opening of the piston to guide axial movement of the poppet valve relative to the piston. A spring (23) is mounted between the valve head and the main piston head for urging the valve head away from the piston head. A control valve (27) moves the piston relative to the valve body between open and closed positions responsive to signals from a computer (72) which signals valve closing upon determination that flow rate through the valve exceeds a maximum period. The spring between the poppet valve head and the piston head exerts a force approximately equal to that of a pressure drop across the poppet valve at a predetermined maximum flow rate.

摘要： 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.

摘要： 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.

摘要： A method for filling a printing ink reservoir with a housing (1) is disclosed, the interior of which is divided into two chambers (3, 4), by means of a metallic bellows (2), serving as a medium separator. The first chamber (3) is filled with a gas and the second chamber (4) is filed with a fluid. A bottom valve (6) is provided n a hydraulic connection (5), the closing body (7) of which may be operated by the medium separator (2), permitting a filling of the second chamber (4) with fluid and preventing a complete emptying of the second chamber (4). According to the invention, a reliable filling of the said chambers (3, 4) with the corresponding medium may be achieved without damaging the bellows (2), by means of a combination of the following method steps: a) evacuation of the second chamber, b) filling the second chamber with printing ink and c) filling the first chamber with the gas.

摘要： The invention relates to a hydropneumatic pressure accumulator, comprising a gas chamber (7), an oil chamber (8) and a pair of metal bellows (9) which separate said chambers. The accumulator has an end plate (11) which is displaced according to volume changes in the gas chamber and oil chamber. Said accumulator is provided with a valve (15) which releases or blocks the flow of hydraulic fluid out of and into the oil chamber (8) and with a valve lifter (23) that controls the valve. During a displacement of the end plate (11), corresponding to a volume expansion in the gas chamber (7) which exceeds a predetermined maximum value, the valve lifter can be displaced by said end plate (11) into a position which blocks the valve (15). Said valve lifter (23) is connected in a fixed manner to the end plate (11) of the metal bellows (9) and the valve (15) can be blocked in two opposing directions by the displacement of the valve lifter (23).

摘要： An improved hydraulic accumulator is introduced wherein a valve mechanism (3) is used to seal a hydraulic fluid before the pressure charged piston (1) reaches the end of the accumulator to minimize the loss of compressed gas by eliminating the pressure differential when the piston (1) is fully extended, thereby prolonging the fatigue life of the accumulator vessel. Reduction of the pressure loading on the vessel will also prolong the life of the piston seals and metal bellows (8) effectively extending the accumulator life and effectively allowing design for weight reduction and preservation of the integrity of the complete hydraulic or pneumatic system.

摘要： Disclosed is an accumulator comprising a cylindrical shell including a cylindrical portion, a partitioning member for partitioning the interior of the shell into a hydraulic chamber and a gas chamber, and a port including a hydraulic fluid flow path for communicating the exterior of the shell and the hydraulic chamber. The variation of the pressure of a hydraulic fluid flowing into the hydraulic chamber is accommodated by expansion and compression of a gas in the gas chamber according to expansion and contraction of the partitioning member. The port is approximately airtightly inserted into the cylindrical portion of the shell, and is welded to an outer circumference of the cylindrical portion by means of welding.
