<p>The invention provides a spray gun for liquids and more especially liquid coatings such as paints and varnishes, comprising a liquid container, a housing, a pump for the supply of the liquid from the liquid container to a spray nozzle via a spring loaded outlet valve, and a return duct connecting the outlet of the outlet valve with the container and having an adjustable valve therein. Pumping may be caused to take place by switch means on the handle. For adjustment of the further valve, which may be preferably completely shut, there is an adjustment member in the front part of the spray gun on the jet side thereof, which is decoupled from the switching on means and, while being able to be steplessly adjusted, is able to remain in each setting of its own accord. This makes it possible for the spray jet to be modified readily without interrupting spraying and even when the spraying density is very low it possible to ensure an even spray cone.</p> |
