摘要： A valve arrangement including a valve housing (10) which includes an inlet port (11) and two outlet ports (12, 13) for fluid flowing through the housing. A valve element (15) is accommodated in a first valve space in the valve housing and movable between two end positions. The valve element includes two surfaces (16), each of which is adapted for co-action with a respective outlet port such as to close an associated outlet port in one and the other of the end positions of the valve element (15). A device (20 or 21 and 26, 47) for resetting the valve element between the positions. The valve element (15) is mounted on one end of a pivotal arm (18) and has the form of a valve plate or disc which includes valve-element surfaces (16) for alternate co-action with a respective outlet port (12, 13). The arm (18) carrying the valve element (15) is connected mechanically to and adapted to drive a further valve element (42), which is accommodated in a separate, second valve space, between two positions in which the further valve element connects one or the other of two fluid inlet ports (43) to a fluid outlet port (45) which is common to the fluid inlet ports.

摘要： A constant flow regulator device for maintaining a constant flow of fluid when a variable fluid pressure is applied, comprising an inlet duct (506) for incoming fluid, a housing (500), and a movable partition (502) facing the inlet duct and being subjected to an elastic force. A fluid passage (510) of variable cross section area is formed between the inlet duct and the movable partition. The housing and movable partition form an inner compartment (504) in fluid communication with the inlet duct for establishing a fluid pressure inside the inner compartment approximately equal to the fluid pressure in the inlet duct. The size of the movable partition is significantly greater than the size of the inlet duct such that, in use, the partition is moved towards the inlet duct against the elastic force when the fluid pressure in the inlet duct increases to reduce said fluid passage cross section area, and vice versa, thereby maintaining constant fluid flow.

摘要： A valve housing (10) includes an inlet port (11) and two outlet ports (12, 13) for fluid passing through the housing. A valve element (15) accommodated in the valve housing is moveable freely between two end positions and has two surfaces (16) each adapted to close a respective outlet port in one and the other of the two end positions of the valve element. The valve element further includes members (20, 22: 21, 22: 21, 26, 47; 26, 48; 26, 50; 26, 51-54) for resetting between the positions. A double-action pump includes two spaces or rooms that have valve-controlled inlets and outlets (39, 40; 29, 30) for drive fluid and pump-transported working fluid respectively. The spaces are divided into an operating chamber (28) and a working chamber (27) by partition walls (26, 36, 37) which are pistons or diaphragms (26) and reciprocatingly move between end positions. The partition walls are interconnected by a movement transmission member (38) and working fluid is pressed out of one of the working chambers and drawn into the other. The operating chamber inlets (39) are each connected to a respective outlet port (12 or 13). The pump includes resetting member which at the end positions causes the valve element (15) to be moved over only a part of its movement path to its opposite end position.

摘要： A double-acting pump having two cavities, each of which is divided into an operating chamber and a working chamber by means of a respective movable partition wall. Each of the operating and working chambers is provided with a valve-controlled inlet and outlet for a gaseous driving medium and a pump-transported liquid working medium. A movement transmission device extends between the movable partition walls and transmits movement of one partition wall to the other and vice versa. This movement transmission device includes a spring element for compression and expansion in the movement transmission direction such that a distance between the partition walls is variable as one partition wall can move independently of the other wall responsive to relative gas pressure in the operating chambers.
