Abstract (en)
[origin: WO2020043329A1] The invention relates to a valve (1) for blocking and releasing a flow path, having: - an electromagnetic actuator unit (5); - an armature (8), which can be axially moved by means of the electromagnetic actuator unit (5), and a closure element (10), which is connected to the armature (8), said closure element (10) being designed to block and release a flow path; - a housing (2), which receives at least the armature (8) and a first closure element (10) axial end (20) connected to the armature (8); and - a housing part (18), which forms a valve seat (16) and against which a second axial end (22) of the closure element (10) is pressed by means of a spring device (17) in a closed position of the valve (1). The spring device (17) has at least one spring (32, 34) which can be compressed at a first spring rate starting from a completely closed position of the valve (1) to a partly open intermediate position of the valve (1) and a spring (32, 34) which can be compressed at a second spring rate starting from a partly open intermediate position of the valve (1) to a completely open position of the valve (1), wherein the first spring rate differs from the second spring rate.
