Definitions

  • a control valve that consists of a slide provided axially slidable in a closed valve chamber, in which in a plane extending substantially perpendicular to the direction of sliding of the slide, the wall of the valve chamber is provided with a number of ports for the connection between the internal space of the valve chamber and the delivery chamber.
  • This control valve is a mixing valve for cold and hot water.
  • This three-way valve is balanced as the pressures of cold and hot water are usually equal.
  • the invention has the object to provide a capacity control valve of the above mentioned type, in which the above mentioned disadvantage and problems are obviated.
  • the magnetizable armature is attached coaxially, cooperating with an electric coil arranged coaxially.
  • a bias spring is provided biasing the slide in the direction from the valve chamber space communicating with the pressure pipe.
  • the space in which the electric coil is arranged, is adjacent to the delivery chamber.
  • a number of ports 9 are provided connecting the valve chamber to the delivery chamber 2.
  • the portion of the valve chamber in which the ports 9 are provided is formed by a cylinder lining 10 pressed in the valve chamber and in the wall of which apertures are bored.
  • the ports 9 are surrounded by a ring-shaped space 11 which may be considered as an extension of the delivery chamber 2.
  • the cylindrical slide 7 has two ring-shaped sealing faces 12, 13.
  • the first sealing face 12 engages the inner wall of the cylinder lining 10, whereas the second sealing face 13 engages a cilindrical wall of the valve chamber portion 4.
  • any known sealing means may be applied.
  • the balancing regarding the pressure in the space 8 acting on the right hand face 20 of the slide 7 is obtained by a continuous passage extending from the right hand end face 20 to the left hand end face 21 of the slide 7.
  • said passage is defined by the clearance between operating rod 22 and the bore 23 of the slide 7.
  • the operating rod 22 may be hollow also and may be provided with a transverse aperture at the location of the space 5. The latter solution is not shown because this is already sufficiently clear in itself.
