  • the valve includes a valve sealing body for selectively opening and closing a valve opening on a valve seat and an opening means for selectively lifting the valve sealing body from the valve seat.

  • Valves in storage devices of hydraulic units, particularly vehicle brake systems, are used to control the amount of pressure fluid within the associated storage device.
  • the storage devices comprise a storage cylinder and a storage piston guided therein, with which a storage volume for the pressure medium is delimited. From the storage volume, the pressure medium can be promoted when needed in a brake circuit. If the storage volume decreases, the accumulator piston moves so deeply into the storage cylinder that it opens a spring-assisted closed valve with an opening means. Pressure fluid then flows into the cylinder again through the opened valve.
  • Conventionally used opening means are designed as a pin, which fits accurately into the storage piston used, in particular pressed. Precisely fitting production is necessary because the opening means for lifting the valve sealing body has to hit it correctly. As a rule, the pin-shaped opening means is guided from the piston side through the valve opening to the valve sealing body.
