AEROSOL INCLINED VALVE AND METHOD OF ITS FORMING Russian patent published in 2002 - IPC

FIELD: mechanical engineering; materials handling facilities. SUBSTANCE: proposed invention relates to valve designed for delivery of products from pressure containers. Aerosol inclined valve has molded hollow rod and molded conical rod cup connected into unit. Upper outer peripheral edge of rod cup usually gets completely into engagement with gasket surrounding the inner wall of rod cup form ring space. At least one formed metering hole located lower than upper edge of rod cup passes from ring space through rod. Rod is molded with provision of ring-shaped cavity around its lower end and at least one metering hole. Molded rod is fitted into forming space. Lower part of ring-shaped screen locks metering hole and, together with forming space and lower part of rod, defines configuration of rod cup. Rod cup is formed with ring projection passing into ring cavity to form single unit strong and fully interconnected with rod. Rod cup and rod unit operate as one part. Invention provides effective operation of inlet metering side hole of valve which should be located inside ring-shaped space surrounding rod and formed by means of sealing gasket and rod cup. This hole should be easily made and its size should by thoroughly checked. EFFECT: improved efficiency of valve in operation. 7 cl, 4 dwg
