Electromagnetically operable hydraulic proportional valve has closing member with in region of end facing valve seat, cone-shaped sealing member whose smaller end faces valve seat

摘要

An electromagnetically operable hydraulic proportional valve (10) has a magnet part (12) made out of an electrically controlled coil (18), a fixed core (28) projecting into the inside of the coil and an armature (38) guided in sliding fashion and acted upon by the coil. This is coupled to a closing member (60). There is a valve part (14) which has a feed channel (50), return channel (52), a working channel (54) and a valve seat (58) that controls in conjunction with the closing member a pressure medium connection between the working channel and the return channel. The closing member has at least in the region of its end facing the valve seat, a cone-shaped sealing member whose smaller end face faces the valve seat. The sealing body at its end facing away from the valve seat has at least one stall edge.
