Abstract
Abstract An electromagnetically operating actuator for control elements capable of making oscillatory movements in displacement machines, more particularly for flat slide shut-off valves and lift valves, includes a spring system and a pair of electrically operating switching elements, over which the control element is movable in two discrete opposite operating positions and is retained thereat by either switching magnet, the locus of the position of equilibrium of the spring system lying between the two operating positions. The invention is characterized by the provision of a compression device in engagement with the spring system for relocating the locus of the position of equilibrium of the spring system upon actuation of the compression device.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
158 words
An electro-magnetically operating adjusting device for oscillatory control elements (6) in displacement machines, in particular for slide-type and lift-type valves, comprising a spring-mass system (6,11,16,17) which comprises the control element (6) and a spring system (16,17) which is in operative connection therewith and preferably comprises two springs acting oppositely to each other, and two electrically operating switching magnets (12, 13), by way of which the control element (6) can be moved into two discrete oppositely disposed switching positions and held there by one of the switching magnets (12 and 13 respectively), characterized in that a clamping device is connected to the spring-mass system (6, 11, 16, 17) in such manner that the static rest position of the spring-mass system (6,11,16,17) can be shifted from a substantially median position between the switching positions of the switching magnets (12, 13) into another location, preferably disposed in the zone of one of the switching positions of the switching magnets (12, 13).
Claim 2
Dependent Claim
158 words
An electro-magnetically operating adjusting device for oscillatory control elements (6) in displacement machines, in particular for slide-type and lift-type valves, comprising a spring-mass system (6,11,16,17) which comprises the control element (6) and a spring system (16,17) which is in operative connection therewith and preferably comprises two springs acting oppositely to each other, and two electrically operating switching magnets (12, 13), by way of which the control element (6) can be moved into two discrete oppositely disposed switching positions and held there by one of the switching magnets (12 and 13 respectively), characterized in that a clamping device is connected to the spring-mass system (6, 11, 16, 17) in such manner that the static rest position of the spring-mass system (6,11,16,17) can be shifted from a substantially median position between the switching positions of the switching magnets (12, 13) into another location, preferably disposed in the zone of one of the switching positions of the switching magnets (12, 13).
Claim 3
Dependent Claim
78 words
An electro-magnetically operating adjusting device according to Claim 1, characterized in that the clamping device has at least two discrete positions, the static rest position of the spring-mass system (6, 11, 16, 17) lying in the substantially median position between the switching positions of the switching magnets (12,13) in the first position of the clamping device, and in the zone of one of the switching positions of the switching magnets in the second position of the clamping device.
Claim 4
Dependent Claim

An electro-magnetically operating adjusting device according to one of Claims 3 or 4, characterized in that the electromagnet (14,15) of the clamping device can be energized more slowly than the switching magnets (12, 13).
Claim 7
Dependent Claim
43 words
An electro-magnetically operating adjusting device according to one of the preceding claims, characterized in that the forces of the switching magnets (12, 13) are greater than the opposing forces of the spring system (springs 16, 17) only shortly before reaching the switching positions.
Claim 8
Dependent Claim
42 words
An electro-magnetically operating adjusting device according to one of the preceding claims, characterized in that a single armature (11), which is connected to the control element (disc valve 6), is arranged between the two switching positions of the switching magnets (12, 13).
