Abstract
Abstract A dosing valve for liquid or pasty products includes a hollow valve body with an inner chamber, a normally open inlet communicating with a recipient of a product, and an outlet normally closed by a spring-urged clapper. Part of the body can be elastically deformed to reduce the volume of the chamber and compress the product therein to close the inlet, open the outlet and deliver a discrete dose of the product.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
193 words
A dosing valve device for liquid and pasty products, comprising a valve body connected to a container for said product, a first inlet orifice communicating the container with the interior of said valve body, the product entering said interior via gravity, a first movable piece cooperating with said inlet orifice, a second outlet orifice provided in said valve body, a second movable piece cooperating with said outlet orifice, a spring urging said second movable piece to a position in which it retains the product from passing from the interior of said valve body through said outlet orifice, wherein said valve body is provided with a flexible wall which can be deformed from a first position in which the first movable piece opens the inlet orifice and the second piece prevents the product from passing through the outlet orifice, into a second position in which the first piece closes the inlet orifice and the second piece permits the passage of the product through the outlet orifice after having been displaced against the action of said spring by the product entering into said valve body and being compressed by the deformation of said flexible wall.
Claim 2
Dependent Claim
193 words
A dosing valve device for liquid and pasty products, comprising a valve body connected to a container for said product, a first inlet orifice communicating the container with the interior of said valve body, the product entering said interior via gravity, a first movable piece cooperating with said inlet orifice, a second outlet orifice provided in said valve body, a second movable piece cooperating with said outlet orifice, a spring urging said second movable piece to a position in which it retains the product from passing from the interior of said valve body through said outlet orifice, wherein said valve body is provided with a flexible wall which can be deformed from a first position in which the first movable piece opens the inlet orifice and the second piece prevents the product from passing through the outlet orifice, into a second position in which the first piece closes the inlet orifice and the second piece permits the passage of the product through the outlet orifice after having been displaced against the action of said spring by the product entering into said valve body and being compressed by the deformation of said flexible wall.
Claim 3
Dependent Claim
55 words
A dosing valve device according to claim 1 wherein the flexible wall of said valve body is formed by a separate membrane element having a horizontal cross section in V form, the angle of the limbs of said V varying by pressing one limb against the other in the axial direction of said movable pieces.
Claim 4
Dependent Claim
27 words
A dosing valve device according to claim 1 wherein said flexible wall is made in one piece with said valve body, said wall being of reduced thickness.
Claim 5
Dependent Claim
94 words
A dosing valve device according to claim 1 wherein said first movable piece is constituted by a disc cooperating with a perforated cover plate including said inlet orifice and connected to said valve body, and wherein said second movable piece is constituted by a disc urged by said spring against a plate intermediate the first and second movable pieces and provided with a third orifice, the flexible wall being deformable from its first to its second position by pressing the end of the valve body adjacent to the outlet orifice towards the inlet orifice.
Claim 6
Dependent Claim
17 words
A dosing valve device according to claim 1 wherein said first and second movable pieces comprise balls.
Claim 7
Dependent Claim
64 words
A dosing valve device accOrding to claim 1 wherein said valve body is fitted under a container of liquid soap mounted on a support adapted to be fixed to a wall, and further comprising a lever pivoted about a transversal shaft, said lever engaging at one end said valve body and cooperating at the other end with a control member actuated by electro-magnetic means.
