Definitions

  • the invention relates to a valve gun for a high-pressure cleaning device for dispensing cleaning liquid, with a housing and a valve arranged in the housing, which has a closing body which is arranged on a valve stem and which in a closed position rests tightly on a valve seat and which by pivoting one on a bearing point pivotably mounted about a first pivot axis release lever against a pressure of the cleaning fluid acting on the closing body can be moved into an open position spaced from the valve seat, wherein the release lever assumes a rest position in the closed position of the closing body and a release position in the open position of the closing body and via a a second pivot axis pivotably mounted coupling lever is mechanically coupled to the valve tappet, a pivoting movement of the release lever being transmitted to the coupling lever via a coupling member movable along a guide track and the guide track has a first end section, an intermediate section and a second end section.
  • the valve gun has a valve with an inlet and an outlet.
  • a pressure hose can be connected to the inlet, and a spray lance, for example, can be connected to the outlet.
  • Cleaning liquid under pressure can be fed to the valve gun via the pressure hose, and the liquid can be directed at an object via the spray lance.
  • the user has the option of pivoting a release lever from a rest position into a release position.
  • the release lever is mounted pivotably about a first pivot axis at a bearing point.
  • the release lever is mechanically coupled to a valve tappet via a coupling lever, on which a closing body of the Valve is arranged.
  • the valve tappet can be connected in one piece to the closing body, but it can also be two separate components. Starting from a closed position in which the closing body is in close contact with a valve seat, the closing body can be moved into an open position spaced apart from the valve seat by pivoting the release lever, the transition of the closing body from the closed position into the open position against the pressure acting on the closing body Cleaning fluid takes place.
  • the pivoting movement of the release lever is transmitted to the valve tappet, on which the closing body of the valve is arranged, via a coupling lever mounted pivotably about a second pivot axis.
  • the transfer of the pivoting movement from the release lever to the coupling lever takes place via a coupling element which can be moved along a guide track by pivoting the release lever.
  • the guideway has a first end section, an intermediate section and a second end section. If the release lever is pivoted from the rest position into the release position, the coupling member moves along the guide track, and this in turn means that the coupling lever also performs a pivoting movement and the valve tappet is displaced as a result.
  • the closing body In addition to the pressure of the cleaning liquid, the closing body is usually acted on by the force of a return spring of the valve, which ensures that the closing body automatically assumes its closed position again after the liquid has been dispensed, provided the user releases the release lever. A considerable force must therefore be exerted on the closing body in order to open the valve.
  • a valve pistol in which the actuating force required to open the valve is reduced in that a piston, on which the pressure of the cleaning fluid prevailing upstream of the valve seat acts, rests on the release lever.
  • the piston is slidable and sealed in a channel.
  • a valve pistol is known in which the release lever is mechanically coupled to the coupling lever via two coupling members, the two coupling members successively contacting different sections of the guideway during a pivoting movement of the release lever.
  • a first coupling member is at a greater distance from the pivot axis of the coupling lever than the second coupling member.
  • a large opening force can be exerted on the valve stem, even if the user only presses the release lever with a relatively low actuating force applied.
  • the large distance between the first coupling member and the pivot axis of the coupling lever has the consequence that during the first phase of the pivoting movement of the release lever, only a small stroke of the valve tappet, i.e. only a relatively small displacement path of the valve tappet, can be achieved.
  • the coupling between the release lever and the coupling lever then takes place via the second coupling member, which is at a smaller distance from the pivot axis of the coupling lever.
  • the smaller distance between the second coupling member has the consequence that when the release lever is pivoted further, a larger displacement path of the valve tappet can be achieved, so that the closing body can be moved to a relatively large distance from the valve seat.
  • the object of the present invention is to develop a valve pistol of the type mentioned at the beginning in such a way that it has a simpler structural design and can nevertheless be actuated in a simple manner by the user, in particular to open the valve.
  • the pivoting direction of the release lever takes place along an imaginary circular arc, the center of which corresponds to the bearing point of the triggering lever and whose radius corresponds to the distance between the contact point of the coupling member on the first end section of the guide track and the bearing point of the triggering lever.
  • the mechanical coupling between the release lever and the coupling lever takes place via a coupling member which, when the release lever is pivoted from the rest position into the release position, moves from the first end section of the guideway via its intermediate section to the second end section of the guideway.
  • the pivoting movement of the release lever is transmitted to the coupling lever, which in turn applies an opening force to the valve stem, under the action of which the closing body of the valve located on the valve stem is moved from the closed position to the open position.
  • the first end section of the guide track in the valve pistol according to the invention is less to the pivoting direction of the release lever inclined than the intermediate section.
  • the smaller inclination of the first end section to the pivoting direction of the release lever has the consequence that the coupling lever initially changes its pivot position only slightly when the release lever is initially pivoted from the rest position, i.e. a change in the pivot angle of the release lever initially only results in a slight change in the pivot angle of the coupling lever.
  • the second end section of the guide track has a smaller inclination to the pivoting direction of the release lever as the intermediate section.
  • the relationship between a change in the swivel angle of the trip lever and a change in the swivel angle of the coupling lever is specified by the inclination of the sections of the guide track to the swiveling direction of the release lever and thus to the imaginary circular arc explained above.
  • the greater the inclination the greater the change in the pivot angle of the coupling lever that can be achieved by changing the pivot angle of the release lever.
  • a slight inclination means that a change in the pivot angle of the release lever has only a small effect on the change in the pivot angle of the coupling lever.
  • a slight inclination also means that the force exerted by the coupling lever on the release lever is aligned essentially radially to the imaginary circular arc explained above, that is, the force is essentially directed to the bearing point of the release lever and not roughly parallel to the pivoting direction of the Release lever. If the second end section of the guide track has a slight inclination to the pivoting direction of the release lever and thus a slight inclination to the imaginary circular arc, the force of the cleaning fluid and the return spring of the valve acting on the closing body in the open position of the valve is essentially radial via the coupling lever Transfer the direction based on the imaginary circular arc to the release lever, so that the user only has to use a small amount of force to hold the release lever in the release position.
  • the second end section of the guide track is aligned parallel to the pivoting direction of the release lever, that is to say tangentially to the imaginary circular arc explained above.
  • Such an alignment of the second end section enables the coupling lever to support itself in the open position of the valve via the coupling member and the second end section in the radial direction in relation to the imaginary circular arc on the release lever.
  • the force to be exerted by the user in the release position of the release lever can thereby be kept particularly low.
  • first end section and / or the intermediate section and / or the second end section are at least partially straight.
  • the transition from the first end section to the intermediate section and / or the transition from the intermediate section to the second end section of the guide track is advantageously curved, so that the first end section merges continuously into the intermediate section and / or the intermediate section merges continuously into the second end section. This facilitates the handling of the valve gun.
  • the coupling member is arranged on the release lever and the guide track is arranged on the coupling lever.
  • the coupling member is arranged on an end face of the release lever facing away from the first pivot axis.
  • the coupling member is arranged on the coupling lever and the guide track is arranged on the release lever.
  • the guide track is arranged on an end face of the release lever facing away from the first pivot axis.
  • the coupling member is preferably designed as a freely rotatable coupling roller.
  • the coupling role can be designed as a single role or in the form of a double role.
  • a double roller can have two roller bodies aligned parallel to one another, which are mounted freely rotatable about a common axis of rotation.
  • a bearing body is arranged between the two roller bodies, on which the two roller bodies are mounted freely rotatable about the common axis of rotation.
  • the bearing body is advantageously connected in one piece with the release lever or in one piece with the coupling lever.
  • the coupling member is designed as a coupling cam which protrudes from the release lever or from the coupling lever.
  • the coupling cam is preferably connected in one piece to the coupling or release lever.

  • the valve has a valve inlet and a valve outlet, the valve outlet protruding from a front side of the housing of the valve pistol, and the housing has a handle that can be grasped by the user, the release lever being in its rest position a rear side of the handle facing away from the valve outlet protrudes.
  • the user can actuate the release lever with the ball of his hand. If cleaning liquid under pressure is dispensed from the valve gun, the cleaning liquid exerts a recoil on the valve gun.
  • the positioning of the release lever on the rear side of the handle facing away from the valve outlet has the consequence that the valve pistol is pressed against the ball of the hand of the user under the influence of the recoil of the cleaning liquid.
  • the ball of the hand of the user thus acts like an abutment on which the valve pistol is supported. This relieves the user's fingers.
  • the housing of the valve pistol has a handle that can be grasped by the user and protrudes from a front, central or rear area of the housing, and if the first pivot axis is in a front, central or rear area of the housing facing away from the housing End portion of the handle is arranged.

  • the valve outlet 30 protrudes from a front side 32 of the housing 12.
  • a spray lance for example, can be connected to the valve outlet 30.
  • a liquid supply line for example a pressure hose, can be connected to the valve inlet 28 and, in the exemplary embodiment shown, can be introduced into the housing 12 via a hose inlet opening 34.

  • the valve inlet 28 is connected to the valve outlet 30 via a flow channel 38.
  • the flow channel 38 forms a valve seat 40 against which a closing body 42 can be placed tightly.

  • a spring holder 48 is fixed on the end region 46 of the valve tappet 44.
  • a first return spring 50 is clamped between the spring holder 48 and the valve housing 26, which applies a spring force to the valve tappet 44, under the action of which the closing body 42 assumes a closed position in which it rests tightly on the valve seat.

  • the release lever 52 is mounted on the two housing shells 14, 16 at a bearing point 64 so as to be pivotable about a first pivot axis 66.
  • the handle 56 has a handle opening 68 on its rear side facing away from the valve 24, via which the release lever 52 with an actuating surface 70 protrudes from the housing 12.
  • the release lever 52 On its end face 72 facing away from the first pivot axis 66 and thus the bearing point 64, the release lever 52 carries a coupling member 74 which, in the in the Figures 1 and 2

  • the closing body 42 is acted upon by the first return spring 50 with a force in the direction of its closed position.
  • the closing body 42 In order to hold the closing body 42 in its open position, the closing body 42 must therefore be acted upon by the coupling lever 54 via the valve tappet 44 with a holding force.
  • the coupling lever 54 is supported on the release lever 52 via the second end section 100 of the guide track 94 and the coupling roller 76.
