Valve intended to be used in particular in inhalation devices having a body, such as a spacer, the valve having a housing comprising an first part which is adapted to be mounted on an outlet opening of the body of the inhalation device, a second part on to which a mouthpiece or a face mask can be mounted, said first and second parts being provided with a first bore defining an inhalation channel, a first membrane provided in the inhalation channel and a second membrane, wherein the second part i...

A valve, includes a housing formed with a valve seat and having an inlet port and an outlet port; and a shut-off member positioned in a passageway between the inlet port and outlet port and so adjustable as to enable a separation of the inlet port and the outlet port from one another when seated on the valve seat, wherein the valve seat exhibits a seat surface which is so inclined in circumferential direction that intersections of diametrically opposed tangents constructed on the seat surface of...

A valve which is formed by a face of a valve body and the outlet area of an opening in a counterpart is disclosed. An extension dipping into the opening to ensure smooth evolution of the beginning of opening operation is known. The opening behavior achieved in this manner is not sufficient for all applications. In order to further smooth the evolution of the beginning of the opening operation, a clearance fit is provided between the extension and the opening which is interrupted by a countersink...

A valve is provided which includes a dispensing spout and a spout insert. The spout insert includes a pair of upwardly extending posts which project up and into the spout. The spout urges the posts towards each other and a valve bridge extends between the posts and overlays a hole defined in the spout insert through which liquid flows when a suction force is applied to the spout. When no suction force is applied to the spout, the valve bridge closes the hole.

A valve for high-pressure radial piston pumps suitable for controlled brake systems. Prior art pumps consist of at least 5 elements. The valve includes less components and thus is less expensive to manufacture and easier to assemble. The valve's simplicity derives from the use of cold extruded connections between the valve and the housing, so that separate rubber sealings are superfluous, and which provide for a strong and non-detachable connection. Favorable embodiments of the present invention...

A one-way valve of simple construction comprises a body provided with appropriate bores and four legs. A ball is positioned between the legs which are then bent towards each other to retain the ball in the body.

Improved valve presents a threaded end, suitable for permitting the positioning of a valve core which is in charge of performing the opening or closing of the passage of air. Over the end threaded portion, a device is mounted with assembly for closing the mouth of the valve and for actuating the valve core, the device including a main body, or a main body and an external body coupleable with each other, a rod and a spring. The device presents a mouth of preferably trunco-conical shape and variou...

A directional-control valve is connectable to a first main pipe and to a secondary pipe. The valve includes an upstream port and a downstream port connectable to the first main pipe and having identical diameters. A third connection port is connectable to the secondary pipe. A shut-off member is capable of moving at right angles to the main pipe between a closed position and a second open position. In the closed position, the shut-off member includes a first orifice, of a diameter identical to t...

A valve for bringing gaseous fuel into the combustion chamber of gas engines is provided with a solenoid valve (8) controlling fuel delivery (7) and an adjoining poppet valve (2), which closes biased by the force of a spring, and which opens in the direction of the combustion chamber through the pressure of in-flowing gas. For the purpose of keeping the poppet valve (2) open, independent from the pressure conditions at its valve head (3), the valve's stem (4) is connected to a step piston (6) wh...

The invention relates to a valve that comprises at least one pump connection (10), one tank connection (14) and one consumer connection (18), and a valve piston (22) that is displaced within the valve box (12). Said valve piston separates the pump connection (10) from the tank connection (14) in at least one blocked position and interacts with an energy accumulator (24). A fluid stream that flows between the consumer connection (18) and the tank connection (14) is controlled by means of a contro...
