Definitions

  • this is achieved by means of a cover plate guided slidably in the cylinder and forming a confining surface for the displacement medium, the said cover plate being supported against the adjacent end wall of the cylinder by way of a spring.
  • the return of the displacement piston can take place in a substantially shorter time than is the case of the construction described in said patent referred to above, since the cover plate forming the forward confining surface for the displacement medium is supported resiliently in the direction of movement of the piston, i.e. in the direction of the front end wall of the cylinder.
