Definitions
- the invention relates to a valve gun for a high-pressure cleaning device for dispensing cleaning fluid, comprising a housing and a valve disposed in the housing, which has a closing body which is arranged on a valve stem and in a closed position against a valve seat tightly and by pivoting on a bearing point about a first pivot axis pivotally mounted release lever is movable against a force acting on the closing body pressure of the cleaning liquid in a valve seat spaced open position, wherein the release lever in the closed position of the closing body assumes a rest position and in the open position of the closing body a release position and on a order a second pivot axis pivotally mounted coupling lever is mechanically coupled to the valve stem, wherein a pivoting movement of the release lever via a movable along a guide path coupling member the coupling lever is transferable and the guide track has a first end portion, an intermediate portion and a second end portion.
- valve gun By means of such a valve gun, the discharge of cleaning liquid pressurized by a high-pressure cleaner can be controlled.
- the valve gun has a valve with an inlet and an outlet.
- a pressure hose can be connected to the inlet and, for example, a spray lance can be connected to the outlet.
- About the pressure hose of the valve gun pressurized cleaning fluid can be supplied, and on the
- the liquid can be directed to an object.
- the user has the opportunity to pivot a release lever from a rest position to a release position.
- the release lever is pivotally mounted for this purpose at a bearing point about a first pivot axis.
- About a coupling lever of the release lever is mechanically coupled to a valve lifter on which a closing body of the Valve is arranged.
- the valve stem may be integrally connected to the closing body, but it may also be two separate components.
- the closing body can be moved by pivoting the release lever in a valve seat spaced open position, wherein the transition of the closing body from the closed position into the open position against the pressure acting on the closing body of the Cleaning liquid takes place.
- the pivotal movement of the release lever is transmitted via a pivotable about a second pivot axis coupling lever mounted on the valve stem on which the closing body of the valve is arranged.
- the transmission of the pivoting movement from the release lever to the coupling lever via a coupling member which is movable by pivoting the release lever along a guideway.
- the guideway has a first end portion, an intermediate portion and a second end portion. If the release lever is pivoted from the rest position to the release position, then the coupling member moves along the guideway, and this in turn has the consequence that the coupling lever also performs a pivoting movement and thereby the valve tappet is displaced.
- a valve gun is known in which the actuation force required to open the valve is reduced by the fact that a piston, on which the pressure prevailing upstream of the valve seat of the cleaning fluid acts on the release lever.
- the piston is slidably mounted and sealed in a channel.
- a valve gun is known in which the release lever is mechanically coupled via two coupling members with the coupling lever, wherein the two coupling members in succession contact different sections of the guideway during a pivoting movement of the release lever.
- a first coupling member in this case has 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 releases the trigger lever only with a relatively low operating 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 pivotal movement of the trigger lever only a small stroke of the valve stem, that is, only a relatively small displacement of the valve stem can be achieved.
- Object of the present invention is to develop a valve gun of the type mentioned in such a way that it has a simpler design and yet can be operated by the user in particular to open the valve in a simple manner.
- the pivoting direction of the release lever is along an imaginary circular arc whose center corresponds to the bearing point of the release lever and whose radius corresponds to the distance between the contact point of the coupling member at the first end portion of the guide rail and the bearing point of the release lever.
- the mechanical coupling between the release lever and the coupling lever via a coupling member which moves during pivoting of the release lever from the rest position to the release position, starting from the first end portion of the guideway over the intermediate portion to the second end portion of the guideway.
- the pivotal movement of the release lever is transmitted to the coupling lever, which in turn acts on the valve stem with an opening force, under the action of which is arranged on the valve lifter closing body of the valve is moved from the closed position to the open position.
- the first end section of the guide track is less inclined to the pivoting direction of the triggering device.
- Pivoting direction of the release lever and thus to the above-explained imaginary arc facilitates the user handling the valve gun when opening the valve.
- the use of a during the entire pivoting movement of the release lever from the rest position to the release position, the guideway contacting coupling member allows this a relatively simple structural design of the valve gun.
- the second end portion of the guide track has a smaller inclination to the pivoting direction of the release lever as the intermediate section.
- Pivoting angle change of the coupling lever predetermined.
- a slight inclination has the consequence that a pivot angle change of the release lever has little effect on the change in the pivot angle of the coupling lever.
- a slight inclination has the consequence that the force exerted by the coupling lever on the trigger lever is substantially aligned radially with respect to the imaginary circular arc explained above, that is, the force is directed substantially to the bearing point of the trigger lever and not approximately parallel to the pivoting direction of the release lever.
- the force of the cleaning fluid and the return spring of the valve in the open position of the valve essentially acts radially in the radial direction on the closing body Direction transferred to the imaginary arc on the release lever, so that the user must spend only a small amount of force to hold the release lever in the release position.
- the second end portion of the guide track is aligned parallel to the pivoting direction of the release lever, that is tangent to the above-mentioned imaginary circular arc.
- Such alignment of the second end portion allows the coupling lever to be supported in the open position of the valve via the coupling member and the second end portion in the radial direction relative 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 thus be kept particularly low.
- the first end portion and / or the intermediate portion and / or the second end portion are at least partially configured rectilinear.
- transition from the first end portion to the intermediate portion and / or the transition from the intermediate portion to the second end portion of the guideway is advantageously arcuate, so that the first end portion merges continuously into the intermediate portion and / or the intermediate portion continuously into the second end portion. This facilitates the handling of the valve gun.
- the coupling member is arranged in an advantageous embodiment of the invention on the release lever and the guide track is arranged on the coupling lever.
- the coupling member is disposed on an end face remote from the first pivot axis of the release lever.
- 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 roller can be designed here as a single role or in the form of a double role.
- a dual role may have two parallel aligned roller body, which are freely rotatably mounted about a common axis of rotation.
- a bearing body is arranged, on which the two roller bodies are freely rotatably mounted about the common axis of rotation.
- the bearing body is conveniently integrally connected to the release lever or integral 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 integrally connected to the coupling or release lever.
- the coupling member which may be configured in particular as a freely rotatable coupling roller, is arranged on the end of the coupling lever facing away from the valve.
- the valve has a valve inlet and a valve outlet, wherein the valve outlet protrudes from a front side of the housing of the valve gun, and the housing has a handle gripped by the user by hand, the release lever in its rest position protruding from the valve outlet rear side of the handle protrudes.
- the user can operate the release lever with his palm. If pressurized cleaning fluid is released from the valve gun, the cleaning fluid exerts a recoil on the valve gun. The positioning of the release lever on the back of the handle facing away from the valve outlet results in the valve gun being pressed against the user's palm under the influence of the recoil of the cleaning fluid. The palm of the user thus acts in the manner of an abutment against which the valve gun is supported. The user's fingers are thereby relieved.
- the housing of the valve pistol has a handle which can be grasped by the user by hand, which protrudes from a front, central or rear region of the housing, and if the first pivot axis faces away from the front, central or rear region of the housing End region of the handle is arranged.
- the housing of the valve gun conveniently has two housing shells, on which the release lever is pivotally mounted about the first pivot axis.
- the coupling lever is pivotably mounted on a valve housing about the second pivot axis.
