Preferably, the valve is a metering valve.

The metered dose valve comprises an inlet valve, a metering chamber and an outlet valve.

The vessel (20) includes a metered valve and a depressible valve stem.

A discharge device with a metered dose valve is proposed.

A compact meter-out flow rate control valve having a regenerative function.

At the same time, this makes it possible to use a single metering valve which actuates a whole group of injectors for metering the additional liquid.

At the same time, this makes it possible to use a single metering valve which actuates a whole group of injectors for metering the additional liquid.

A medicinal aerosol product having a blockage resistant metered-dose valve with a metal valve stem, particularly for use with CFC-free solution formulations using hydrogen-containing propellants, such as 134a and/or 227, and ethanol.

The present invention relates to a novel design for a metering valve that provides improved consistency of formulation delivery.

A metering valve (1) is provided for a pressurised container (14) containing a pharmaceutical formulation.

When the body (10) is deformed, flow is from B to A. A double acting valve consists of two such valves and can be constructed as a dosing valve.

The rod is further maintained in a closing position of the dosing valve by a pressure spring (11).

The invention relates to a volumetric metering valve for liquid and viscous substances, comprising a valve body (10) and a valve cylinder (12) in which a piston is displaceably mounted.

The dispenser includes a solenoid metering valve and electronic actuating circuitry in the lid or cap of the aerosol container.

The dispensing valve (40) which controls the emptying aperture is provided to assure the measured discharge of liquid from the supply onto the oblique surface.
