Definitions

  • the invention relates to a valve arrangement for inflating and deflating an air cushion, in particular for ski boots, in which a pump can be actuated on the outside of the shell or the inner shoe, with at least one inlet valve designed as a check valve for the pump chamber and at least one designed as a check valve Exhaust valve from the pump room, the air cushion being emptied via a valve.
  • valve arrangements of this type it has previously been customary to provide a valve which can be actuated from the outside and is connected directly to the air cushion and via which air can be discharged from the air cushion.
  • the pump itself was connected to an inlet valve and connected to the air cushion via an outlet valve. It was therefore usually necessary to lay a hose line from the air cushion to the outlet valve for venting the air and a separate hose line to the outlet valve of the pump.
  • the two valves of the pump, the inlet valve and the outlet valve were mostly designed as simple flap valves, which resulted in a relatively low tightness of the arrangement. Depending on the outside temperature, the valves changed their characteristics and such flap valves are also prone to vibration, so that air can escape uncontrollably in the event of hard blows.
  • the invention now aims to simplify the arrangement of the type mentioned and to keep it structurally more compact while at the same time creating the possibility of using precisely functioning valves.
  • the invention essentially consists in the fact that with the pump chamber an externally operable inlet valve and with the actuator of the inlet valve in a non-positive manner Connection operable outlet valve is connected, to which the air cushion is connected, that both valves are accommodated in a common component, that the valves are designed as spring-loaded valves, in particular poppet valves, and that the valves are arranged one behind the other in the opening direction, leaving a valve stroke free.
  • Such an arrangement makes it possible to find sufficiency for inflating and deflating an air cushion with only two valves.
  • the second valve can also be opened by actuating only one valve after a predetermined stroke, so that air can be released from the air cushion via both valves .
  • a separate outlet valve for the air cushion is therefore unnecessary.
  • spring-loaded valves, in particular poppet valves, such as are used as tire valves, for example, are used in this configuration instead of the flap valves that are usually used, are much more precise and temperature-independent in relation to the tightness in the closed state and in relation to the opening pressure than in the case of reached the normally used flap valves.
  • the arrangement according to the invention is advantageously made such that the valves are arranged coaxially to one another and in the axial direction to one another while leaving a valve stroke free.
  • the arrangement can be such that the axes of the two valves intersect each other at approximately a right angle, the transmission of motion being accomplished from the inlet valve to the outlet valve for the arbitrary emptying of the air cushion over inclined planes on the valve rods. In this way, the inlet valve during the suction stroke of the pump open the pump without operating the pump outlet valve through which the air is to flow into the cushion.
  • the inlet valve is pressed against its seat under the force of the spring and, since it is designed as a check valve, is additionally held in this closed position by the pump pressure.
  • the outlet valve of the pump opens against the force of a spring and the air can get into the cushion.
  • the outlet valve of the pump reaches the closed position under the force of the springs, supported by the pressure built up in the air cushion, and air can be sucked in again by means of the pump via the inlet valve.
  • the inlet valve of the pump is actuated and opened from the outside.
  • valve cone comes into collision with the actuating element of the outlet valve of the pump following coaxially and in the axial direction, and this valve is also opened so that the air can now escape from the cushion via the two opened valves.
  • both valves are closed one after the other and if both valves are closed quickly, the pressure in the air pump and the cushion is approximately the same. It can thus be started immediately afterwards, if desired, with a pump stroke of the pump without it being necessary to build up a corresponding pressure by repeatedly depressing a pump, for example formed by a balloon, which in turn serves as a non-return valve to the cushion can overpress.
  • a structurally compact design is achieved in that the two valves are connected to a T-piece, and the two valves can be screwed, glued or welded into the T-bar of this T-piece. It is preferred to design the T-piece with an internal thread, since this is where the commercially available tire valves come in can be set, which are also usually screwed.
  • the pump which is usually designed as a balloon pump, generally consists of elastomeric plastic.
  • the pump By choosing suitable wall thickness of the plastic in the area of the connection piece to the valves, it is easily possible to form the T-piece in one piece with the pump, so that it is only necessary to form the two valves in the T-bar of the piece with the pump Screw the T-piece.
  • the valves are easily accessible and replaceable from the outside.
  • the design according to the invention is such that the outwardly projecting end of the actuating rod of the inlet valve of the pump in the direction of Valve stroke is longer than the valve stroke and, when actuated in the axial direction against the force of a spring, comes into contact with the actuating rod of the second valve after a predetermined stroke.
  • the design according to the invention makes it possible in a particularly advantageous manner to arrange two identical valves one behind the other in the same direction.
  • a particularly advantageous and compact design results when the pump surrounds the component carrying the valves and is penetrated by this component, the bore of this component receiving the valves being connected to the pump chamber via openings opening between the two valves.
  • FIG. 1 shows a first embodiment of the valve arrangement according to the invention with coaxially arranged valves
  • FIG. 2 shows an embodiment in which the axes of the valves form a right angle with one another
  • FIG. 3 shows an embodiment in which the pump is integral with the receiving part for the valves is formed.
  • Fig. 1 denotes a balloon pump, with which a T-piece 2 is connected in one piece.
  • Two valves 3 and 4 are screwed into the T-bar of the T-piece 2, the valve 3 being the inlet valve and the valve 4 being the outlet valve of the pump.
  • the valve 3 is designed as a spring-loaded poppet valve, the spring being indicated schematically at 5. This valve opens inwards as soon as a suction pressure is exerted by the pump 1 and is again pulled into the closed position by the force of the spring 5. During a suction stroke, the sucked-in air reaches the inside of the pump 1 in the direction of arrow 6.
  • the air can be pressed out in the direction of arrow 7, the second valve 4, the outlet valve of the pump, in the sense arrow 7 opens.
  • This valve is designed as a spring-loaded poppet valve and, after the valve has been closed, enables a high degree of pressure retention inside an air cushion 8.
  • the actuating element 9 of the inlet valve 3 of the pump is depressed in the direction of arrow 10 , After a first valve stroke, the sealing element 11 of the first valve 3 collides with the actuator 12 of the second valve 4.
  • the two valves 3 and 4 are accommodated in an accommodating component 14 at an angle of approximately 90 °.
  • the balloon pump 1 is in turn connected to this component 14.
  • the valves 3 and 4 are essentially identical in construction to the valves shown in FIG. 1.
  • Connected to the sealing element 11 of the first valve 3 is a coupling part which has an oblique control surface 15 and which cooperates with the actuating element 12 of the second valve 4. Depressing the actuating member 9 in the direction of arrow 10 leads via the inclined surface 15 to open the valve 4 in the direction of arrow 16. Otherwise, the function of the valve corresponds to the function of the valves according to FIG.
  • the balloon pump 1 is formed in one piece with the component 14 receiving the valves 3 and 4.
  • the valves can be connected to the rubber-like material of the component 14 receiving the valves by means of undercuts, as are also used in hose nozzles.
  • the pump is made open on one side in this embodiment. After removal of the mandrel, the bottom 17 is glued or welded to the rest of the balloon pump 1. With 18 the line to the air cushion is designated.
  • FIG. 4 A particularly simple embodiment is shown in FIG. 4, in which a component carrying the two valves 3, 4 passes through the pump chamber of the pump 1.
  • the two valves 3 and 4 are in turn arranged coaxially one behind the other, the axial bore of the component receiving these valves 3, 4 being connected to the pump chamber of the pump 1 via radial openings between the two valves.
  • the flow paths are again designated 6 and 7.
