Activating mechanism for an intercept valve for a spray gun used in water cleaner apparatus
The activating mechanism comprises a manually-operated control lever rotatably constrained at a first end thereof to a pivot arranged in proximity of a front portion of a handle grip of a spray gun and an activating lever acting on a pusher element of an intercept valve. The activating lever has a first end portion which is rotatably constrained on a hinging pivot arranged in proximity of a back portion of the handle grip and a second end portion which is operatively constrained to the control lever.
1. A spray gun for water cleaner apparatus, comprising:
an intercepting valve; and
an activating mechanism for the intercept valve,
the activating mechanism comprising
a manually-operated control lever hinged at a first end thereof to a pivot arranged in proximity of a handle grip of the spray gun for opening the intercepting valve, and
an activating lever which acts on the intercept valve and exhibits a first end portion which is pivoted to a hinging pivot arranged in proximity of a back portion of the handle grip and a second end portion which is constrained to the control lever by a contact coupling,
wherein the activating lever exhibits a length which places the second end portion in contact with the control lever along an axis passing through the pivot of the control lever and the hinging pivot of the activating lever when the spray gun is in a first rest position, wherein the first rest postion defines an arrangement of the activating mechanism corresponding to a closed position of the intercepting valve.
2. The spray gun of claim 1 , wherein the control lever exhibits a groove for slidably housing the second end portion of the activating lever.
3. The spray gun of claim 1 , wherein the activating lever is associated to a pin arranged in contact with a pusher element of the intercept valve.
4. The spray gun of claim 1 , wherein it comprises an elastic element interpositioned between the activating lever and the handle grip for obtaining a return of the mechanism into a rest position thereof.
5. A spray gun for water cleaner apparatus, comprising:
a handle grip with a back portion;
an intercepting valve; and
an activating mechanism operatively connected to the intercept valve,
the activating mechanism comprising
a manually-operated control lever hinged at a first end thereof to a pivot arranged in proximity of the handle grip, the control lever opening the intercepting valve, and
an activating lever operatively connected to act on the intercept valve so that a first end portion is pivoted to a hinging pivot arranged in proximity of the back portion of the handle grip and a second end portion which is constrained to the control lever by a contact coupling,
wherein the activating lever has a length which places the second end portion in contact with the control lever along an axis passing through the pivot of the control lever and the hinging pivot of the activating lever when the spray gun is in a first rest position.
