Abstract
A fluid reservoir for a spray gun, which fluid reservoir has a material outlet which is configured for the direct and/or indirect connection to a spray gun. The fluid reservoir has a ventilation device, via which air can flow into the fluid reservoir in order to ensure a pressure compensation when coating material flows out from the fluid reservoir via the material outlet. Advantageously, the ventilation device includes a device on the outside of the fluid reservoir and separately to a ventilation opening and a latching device, which device cooperates as a centering device, a retaining device and/or a guide device with the closure element.
Claims21
A flow cup for a spray gun, the flow cup comprising:
- a material outlet configured for at least one of direct and indirect connection to the spray gun,
- a ventilation device via which air can flow into the flow cup in order to enable pressure equalization when coating material flows out of the flow cup via the material outlet,
- wherein the ventilation device comprises a closure element which is movable between at least one open position, in which air can flow into the flow cup, and a closed position in which no air can flow through the ventilation device into the flow cup, the closure element having a closure plug which, in the closed position of the closure element, closes a ventilation opening in the flow cup,
- wherein the ventilation device further comprises a latching device provided separately from the ventilation opening by means of which the closure element can be held in a latching manner at least in the closed position,
- wherein provided separately on an outside of the flow cup at a spacing from the ventilation opening and from the latching device is a separate centering, retaining and/or guiding device which as a centering, retaining and/or guiding device interacts with the closure element, and
- wherein at least in the closed position a portion of the closure element contacts an inner peripheral surface of the latching device and an outer peripheral surface of the separate centering, retaining and/or guiding device.
