Abstract
A two-component cross valve for controlling the fluid flow through a fluid conduit, the cross valve being injection-molded in two steps with no need for assembly after the injection molding procedure. The valve comprises a valve house with a plug inside it, and it has sealing means in the form of variations in the transverse sectional area of the plug and house along their lengths. Thereby, a cross valve is obtained which does not require a viscous sealant, such as silicone, to eliminate the risk of leakage, when the valve is open.
Claims20
A two-component cross valve for controlling fluid flow through the cross valve, the cross valve comprising:
- a valve house, the valve house comprising a fluid inlet, a body, and a fluid outlet, the valve house being diecast from a first material, and the valve house being a single article;
- and
- a plug, the plug comprising a wall and an opening channel extending through the plug, the plug being diecast from a second material, and the plug being a single article,
- wherein the valve house is one of a first or a second component of the two-component cross valve and the plug is the other one of the first or the second component of the two-component cross valve, the first component having been injection molded directly contacting the second component and the final two-component cross valve, the two-component cross valve having only the first material and the second material,
- wherein the plug is placed inside the body of the valve house,
- wherein the plug is coaxially displaceable in the valve house,
- wherein the cross valve can be opened or closed to fluid flow,
- wherein the cross valve comprises at least one seal configured to seal the cross valve when open to fluid flow, and
- wherein the at least one seal comprises variations in a transverse sectional area of the plug along a length of the plug.
