Definitions

  • present invention relates to the control equipment of pneumatic devices and more particularly the control equipment of pneumatic cylinders.
  • the object of the present invention is to remedy these drawbacks. It makes it possible to take out a jack rod at a moderate speed and then, when this rod is out, it allows the filling of the jack to be finished at the maximum air pressure a very short time. Thus, thanks to the moderate speed of the cylinder rod there is no shock or noise / vibration during the movement. In addition, this cylinder can provide its effort at the end of the rod stroke without delay since the air pressure very quickly reaches that of the supply network.
  • the device, object of the present invention has the advantage of being compact and of being installed between the control valve and a chamber of the jack without modifying the rest of the pneumatic circuit or the devices which compose it. It can be added easily to an existing installation.
  • FIGS. I, 2 and 3 represent the device in its three phases of the operating cycle.
  • the body I is provided with two orifices, one A connected to the control distributor cylinder and the other B connected to chamber II of the cylinder.
  • the distributor lets air pass in the direction of the device, this air passes through channel C at a flow rate adjusted by the needle screw 5 towards chamber II of the cylinder the piston of which moves.
  • a small part of this air is deflected towards the chamber 9 of the device along the path E through a restriction adjustable by a needle screw 6 .
  • the pressure in this chamber 9 becomes sufficient to push the piston 3, the latter compresses its return spring 8 (see FIG.
  • the actuating actuator of the valve is controlled by an air flow coming from a control member external to the device, for example a valve actuated when the rod of the actuated actuator has reached a certain position.
  • the arrangement of the air flows can be done differently.
  • the return of air from the actuated cylinder can be done by a channel F going directly from B to A and which opens automatically in that sense.
  • the channel D then only has a function of passing from A to B when it is opened by the jack constituted by the chamber 9 and the piston 8.
  • device, object of the invention can be used in all cases where one wants to send compressed air to a pneumatic device such as a jack in two stages: in the first, the flow is low and allows the rod to come out at a moderate speed, in the second stage, the air flow is much greater and allows the cylinder to quickly have all the compressed air pressure from the supply network.
