Definitions

  • the invention relates to a pneumatically driven, reversible motor, for example, for a hoisting implement, comprising ports connected with two supply ducts for the forward and return run respectively, the feed being controlled by means of a pneumatic control-circuit.
  • the invention has for its object to provide a motor with an improved pneumatic control so that the pneumatic motor is capable of rotating with variable speeds in one sense as well as in the other in both the loaded state and the no-load state.
  • the motor embodying the invention is distinguished in that at least one feed duct includes a proportionally operating reducing valve, which is controlled by means of a control-duct with a manually actuated, proportionally operating reducing valve.
  • the two feed ducts to the pneumatic motor include a proportionally operating reducing valve, each having its own control-circuit.
  • a by-pass ducts is arranged parallel to one feed duct, in which the by-pass duct and the other feed duct can be alternately connected and set free respectively with the source of pressure by means of a five-port control-valve and in which said one feed duct or the by-pass duct can be connected with the motor by means of a three-port valve.
  • reference numeral 1 designates the reversible pneumatic motor with the ports of which are individually connected feed ducts communicating with a source of pressure D.
  • each feed duct is provided with a proportionally operating reducing valve 2 and 2', which valves can be actuated by their own control-circuits 3 and 4.
  • the control-circuit 3 includes a manually actuated, proportionally operating reducing valve 5 and 6 respectively.
  • valve 5 By depressing, for example, valve 5 the valve 2 will open further at an increasing pressure in the duct 3 so that an increasing pressure will act on the motor. As a result the motor will turn to the right, for example.
  • the pressure in the duct 4 increases so that the counter-pressure on the motor also increases.
  • the speed of the motor is controlled in one sense or the other. It is thus possible to cause the motor to hoist and the veer at full speed or at lower speeds. It is preferred to simultaneously depress or release respectively the valves 5, 6 by means of a mechanical leverage 7.
  • the pneumatic control-circuit part for the brake of the motor included in the diagram is of a conventional type and is left out of consideration.
  • Fig. 2 shows an embodiment in which the two feed ducts of the motor 1 are connected with the source of pressure D; only one feed duct 8 is provided with a proportionally operating reducing valve 2.
  • Parallel to the duct 8 is arranged a by-pass duct 9, which can be connected together with the other feed duct with the source of pressure by means of a five-port valve 11.
  • This five-port valve 11 can be moved by means of a control-circuit 12 into the left-hand or righthand position respectively so that the motor 1 can be alternately rotated to the left or to the right.
  • the control-circuit system 12 os of a conventional type and lies beyond the scope of this invention.
  • the proportionally operating reducing valve 2 in the feed duct 8 is controlled in the same manner as indicated in the foregoing diagram by means of a manually actuated reducing valve 5' so that with an increasing pressure in the control-duct 3 the valve 2 will further open.
  • the duct 8 is connected with the motor 1 by means of a three-port valve 12, which is controlled by a three-port valve 13, which in turn is controlled by the control-duct 3.
  • the control-duct to valve 12 is energized so that the feed duct 8 adjoins the motor 1.
