Definitions

  • the advantage of such a system resides in that the system itself has a storage-effect or accumulator-effect with the exhaust-member, and therefore functions to equalize pulsations, or, this effect is obtained by means of installation of accumulators, pressure-storages, etc.
  • This means that the liquid pressure in the system itself is always positive when using a single-piston pump or fluid motor, and, in so far as once it has exceeded a certain pressure, it retains the control valve positively in an OFF switch-position.
  • a hydraulic pressure-system comprising at least one pump having means for periodically generating hydraulic pressure, said pump means including a variablevolume pressure-chamber having fluid control inlet and outlet means, an automatically-functioning air-exhaust means operatively connected to said variable-volume chamber by throttle means connected in series with said variable-volume chamber and including valving means having a portion normally communicating with liquid at atmospheric pressure, said air exhaust means including means normally biasing said valving means to a valve-open condition whereby air relief is provided for said variable-volume chamber prior to hydraulic pressure build-up, said variable-volume chamber outlet means communicating with said valving means and subjecting it to hydraulic pressures generated therein and subjecting said valving means to said hydraulic pressure in opposition to said means normally biasing the valving means to the valve-open condition or urging the valving means to a valve-closed position at predetermined hydraulic pressures.
