Abstract

The disclosure relates to a pistol pump for delivering fluids comprising a piston, a cylinder element, and a pressure chamber arranged between an inlet valve and an outlet valve. The pressure chamber is closed off by a cover. The outlet valve comprises a closing body, a preload device which acts on the closing body, and a supporting mechanism configured to support the preload device. The outlet valve is arranged on the outer circumference of the cylinder element and adjusts a fluid flow conducted through at least one outflow opening between the cover and the cylinder element. The closing body is configured as a movable annular disk guided on the cylinder element, the inner diameter of which annular disk is matched to the outer diameter of the cylinder element.
