Electro hydraulic pressure control valve for pilot control of e.g. hydraulic control valve, has glued sealant that is provided between surface of valve sleeve and surface of plastic housing when valve sleeve is welded

摘要

The valve (1) has plastic housing (5) that encloses coil (6) of electromagnet (2). A valve sleeve (3) is partially sealed inside the housing. A hydraulic device (7) is flanged or partially inserted into the housing. Fluid-conducting channels (9,10) connected to hydraulic device are arranged in interface between the valve sleeve and housing. A glued sealant (8) is provided between surface of valve sleeve and surface of plastic housing when the valve sleeve is welded. An independent claim is included for a method for manufacturing electro hydraulic pressure control valve.
