Valve with electrodynamic actuator

Abstract

A valve comprising an electrodynamic actuator having a magnet arrangement to generate a magnetic field and a drive element movable relative to the magnet arrangement. The drive element is pivotally mounted and comprises a current-carrying air coil disposed in the magnetic field, and which is fixedly coupled to a coil carrier of a non-magnetic material. Sealing surfaces of sealing valve seats are arranged on two opposite sides of the drive element. The drive element is elongated, and wherein a direction of longitudinal expansion of the drive element extends substantially along a longitudinal expansion of the coil.

1 . A valve with an electrodynamic actuator comprising:
 a magnet device that generates a magnetic field; and   a drive element movable relative to the magnet device,   the drive element being pivotally mounted and comprising a current-carrying air coil ( 54 ) that is arranged in the magnetic field and is fixedly coupled to a coil carrier made of a non-magnetic material,   and wherein sealing surfaces of sealing valve seats are arranged on two opposite sides of the drive element,   and wherein the drive element is elongated, wherein a direction of longitudinal extension of the drive element extends substantially along a longitudinal extension of the coil.   
     
     
         2 . The valve according to  claim 1 , wherein the drive element is encased in an elastomer part. 
     
     
         3 . The valve according to  claim 2 , wherein the elastomer part comprises two sealing sections arranged on the sealing surfaces of the drive element. 
     
     
         4 . The valve according to  claim 2 , wherein the elastomer part has a pear-shaped section and a tongue-shaped section, the tongue-shaped section projecting into the pear-shaped section and encasing the drive element. 
     
     
         5 . The valve according to  claim 2 , wherein the elastomer part has a mounting aid. 
     
     
         6 . The valve according to  claim 1 , wherein the sealing valve seats comprise two valve seats that face each other. 
     
     
         7 . The valve according to  claim 1 , wherein the drive element has a toothing, the coil carrier being firmly connected to the drive element via the toothing. 
     
     
         8 . The valve according to  claim 1 , including a housing formed at least partially from plastic and partially from a metallic encasement. 
     
     
         9 . The valve according to  claim 8 , wherein the housing comprises at least two plastic parts which engage in one another, the metallic encasement being put over the at least two plastic parts in order to hold the at least two plastic parts together. 
     
     
         10 . The valve according to  claim 8 , wherein the metallic encasement is formed from a magnetically conductive steel and serves to shield the valve. 
     
     
         11 . The valve according to  claim 8 , including reinforcing plates made of a soft magnetic material. 
     
     
         12 . The valve according to  claim 11 , wherein the reinforcing plates are arranged inside the housing between the metallic encasement and a permanent magnet, respectively. 
     
     
         13 . The valve according to  claim 1 , wherein the drive element is mounted pivotably about an axis of rotation parallel to main directions of the magnetic fields. 
     
     
         14 . A valve with an electrodynamic actuator, comprising:
 a magnet arrangement to generate a magnetic field; and   a drive element movable relative to the magnet arrangement,   the drive element being pivotally mounted and comprising a current-carrying air coil which is arranged in the magnetic field and is fixedly coupled to a coil carrier made of a non-magnetic material,   and wherein sealing surfaces of sealing valve seats are arranged on two sides of the drive element which do not lie in one plane,   and wherein the drive element is elongated, wherein a direction of longitudinal extension of the drive element extends substantially along a longitudinal extension of the coil.
