Abstract:
A valve for regulating the flow of a liquid or gaseous fluid, the valve comprising:a body having an inlet and an outlet for the fluid;a partition which separates the inlet from the outlet and which includes a cylindrical bore having a circular seat at one end thereof;a valve member that is movable in the axial direction of the circular seat between first and second positions in which the valve is respectively closed and open; andcontrol means functionally connected to said valve member in order to bring it into any desired axial position between its first and second positions so as to regulate the flow of the fluid, said valve member including a first portion which serves as a closure element when the valve member is in its first position, and a second portion which is engaged in said bore and which is shaped to regulate the flow of the fluid at a desired rate depending on the axial position selected for the valve member between its first and second positions,wherein the second portion ofthe valve member is detached from the first portion of the valve member and the second portion has a cylindrical outside surface diameter such that the second portion of the valve member is in sliding contact without friction with the cylindrical surface of said bore, and the second portion of the valve member includes means for bringing the first and second portions of the valve member closer together so as to produce a simple mutual contact and to hold the contact permanently so that the first portion of the valve member and the second portion of the valve member are displaced axially simultaneously and by the same amount under the action of the control means.
