Definitions

  • Actuators are used in various technical fields in order to move movable components.
  • Known actuators comprise a position member and a drive mechanism designed to move the position member.
  • the position member is rotatable around a longitudinal axis of the position member.
  • the US 2002/0130745 A1 describes an electromagnet switching device for underground mining applications.
  • the device comprises two controllable electromagnets accommodated in a case.
  • a cylindrical movable armature is arranged in each electromagnet.
  • Both armatures comprise a central bore into which a switching plunger is screwed.
  • the switching plunger serves for actuating a hydraulic valve.
  • An effective switching lift of the switching plunger is adjustable by screwing the plunger further into or out of the armature.
  • the US 4,518,939 describes an electromagnetic actuator with a solenoid and an armature that moves between two well-defined positions without rotating. Rotation of the armature is prevented by a hexagonal cross-section of the armature. One of the two armature positions is defined by a retainer that protrudes from a housing of the actuator.
  • the objective of the invention is to provide an improved actuator. This objective is achieved by an actuator according to claim 1.
  • an actuator comprises a housing and a drive mechanism arranged therein.
  • the drive mechanism is provided for moving a position member.
  • An outer end of the position member is designed to move a movable component.
  • the actuator further comprises a pin element that projects from the housing.
  • the pin element has a face that is designed to rest against the movable component to prevent a rotation of the movable component.
  • the actuator comprises a metallic yoke and the pin element is part of the metallic yoke. That way, no additional components are needed and no extra assembly process step is necessary for producing the actuator.
  • the pin element is a metallic pin mounted in the housing of the actuator.
  • the plastic material is polyamide.
  • the pin element has a cross-section with the shape of the letter T.
  • the pin element 120 is provided to prevent a rotation of the movable component 106 and/or the position member 103.
  • the pin element 120 rests against the movable component 106. Since the pin element 120 is fixed on the actuator 100, the pin element 120 resting against the movable component 106 prevents a rotation of the movable component 106.
  • the pin element 120 may, for example, rest against a flat surface of the movable component 106. This may have the advantage of low friction between the pin element 120 and the movable component 106.
  • the pin element 120 may as well be bound in a recess of the movable component 106. This may provide a higher friction between the pin element 120 and the movable component 106 but may allow for a better suppression of a rotation of the movable component 106.
  • the pin element 120 may as well be fed through an opening of the movable component 106. This may suppress a rotation of the movable component 106 even better.
