Abstract (en)
[origin: ES279142U] A metering valve adapted to be mounted on a container for delivering a liquid under pressure contained in the container, of the type comprising a metering head with an elastic membrane, an end-sleeve, a valve body and a piston sliding in the valve body and formed with a blind central bore and a radial throughgoing hole opening into the central bore. The valve body is made of two portions, a lower portion positioned to be located inside the container when the valve is mounted on the container and an upper portion applied on the lower portion positioned to be inside the container, but extending outside the container on a major portion thereof when the valve is so mounted. The upper portion of the valve body is formed with a bore in which slides a piston limited upwardly by a shoulder forming an abutment for the piston. The piston is formed with an outer annular groove in its central portion surrounded by two O-rings. The radial throughgoing hole of the piston opens into the annular groove.
