Abstract
A high pressure spraying gun has a jet pipe, a pressure water supply element, two trigger levers for right-handed and left-handed actuation, and only one blocking valve arranged to selectively block and to release pressure water through flow through the jet pipe or through the pressure water supply element and including a valve body, a spring which biases the valve body in a first direction, and a rocking member having two ends spaced from one another in a second transverse direction, so that the blocking valve can be opened only under the simultaneous action of two trigger levers on both ends of the rocking member.
