Abstract
Abstract A dosing valve for liquid product comprises a valve body open in the upper part to receive product and having an outlet orifice at the lower part. An upper disc is displacable above a pierced separating member in a cylindrical housing in the body, the disc being smaller than the housing to leave a gap for the passage of product. The upper disc is displacable, against the action of a spring, from an upper position in which it allows passage of a dose of product towards a lower position in which it stops the passage of product. A lower disc, for controlling the passage of doses of product through the separating member to the outlet orifice, is normally applied against the lower face of the separating member by the difference in the atmospheric pressure acting downstream of the lower disc and a depression created upstream of the lower disc when the upper disc moves from the lower position to the upper position.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
272 words
A dosing valve for liquid product, in particular for liquid soap, comprising a valve body having an upper part and a lower part, the upper part being open to receive product under pressure and the lower part being provided with an outlet orifice, a pierced separating member mounted in the valve body above the outlet orifice, an upper disc displaceable above the separating member in a cylindrical housing having a greater diameter than that of the disc to provide a gap for passage of liquid product, said disc being displaceable betWeen an upper position in which it allows passage of a dose of product to a lower position in which it stops passage of the product, a spring urging the disc towards the upper position, and a lower disc normally applied against the lower face of the separating member at least partially by the difference of the atmospheric pressure acting downstream of the lower disc and a depression created upstream of the lower disc when the upper disc moves from the lower position to the upper position, the lower disc forming means for controlling the passage of doses of liquid product through the separating member to the outlet orifice, and in which the lower disc forms a clapper slidably mounted relative to the separating member, the upper disc being slidably mounted relative to the lower disc, and stop means being provided to prevent the upper disc from moving above the upper position, in which said clapper is mounted on a rod which is slidably mounted in a central bore of the separating member, the upper disc being slidably mounted on said rod.
Claim 2
Dependent Claim
272 words
A dosing valve for liquid product, in particular for liquid soap, comprising a valve body having an upper part and a lower part, the upper part being open to receive product under pressure and the lower part being provided with an outlet orifice, a pierced separating member mounted in the valve body above the outlet orifice, an upper disc displaceable above the separating member in a cylindrical housing having a greater diameter than that of the disc to provide a gap for passage of liquid product, said disc being displaceable betWeen an upper position in which it allows passage of a dose of product to a lower position in which it stops passage of the product, a spring urging the disc towards the upper position, and a lower disc normally applied against the lower face of the separating member at least partially by the difference of the atmospheric pressure acting downstream of the lower disc and a depression created upstream of the lower disc when the upper disc moves from the lower position to the upper position, the lower disc forming means for controlling the passage of doses of liquid product through the separating member to the outlet orifice, and in which the lower disc forms a clapper slidably mounted relative to the separating member, the upper disc being slidably mounted relative to the lower disc, and stop means being provided to prevent the upper disc from moving above the upper position, in which said clapper is mounted on a rod which is slidably mounted in a central bore of the separating member, the upper disc being slidably mounted on said rod.
Claim 3
Dependent Claim
45 words
A valve according to claim 1, in which the cylindrical housing is provided in the valve body, and the upper disc is displaceable from the upper position against the stop means to the lower position in engagement with a peripheral flange on the separating member.
Claim 4
Dependent Claim
32 words
A valve according to claim 2, in which the clapper is provided with peripheral notches to allow a dose of liquid product to pass when the clapper is in a lowered position.
Claim 5
Dependent Claim
36 words
A valve according to claim 2, in which the upper part of the cylindrical body has a conical edge forming an external peripheral shoulder able to hook into the neck of a recipient for liquid product.
