Abstract (en)
A trigger gun (1) for a high-pressure washer is disclosed, where the trigger gun comprises a handle (2), a valve (3) rigidly supported by the handle and a trigger mechanism. The valve further comprises an actuation element (6) for the opening and closing the valve, and the trigger mechanism provides a cooperation between the trigger and the actuation element. The trigger gun (1) further comprises a rocker arm (8) having a second area or point of contact for cooperation with the actuation element, a primary elbow link (37), and a secondary elbow link (38). The trigger mechanism further comprises a primary mechanical linkage constituted by the handle (2), trigger (4), primary elbow link (37), and rocker arm (8) that are pivotally connected in a closed loop, and a secondary mechanical linkage constituted by the handle (2), trigger (4), secondary elbow link (38), and rocker arm (8) that also are pivotally connected in a closed loop. The primary mechanical linkage is employed when changing the valve from a closed state to a first open state and the secondary mechanical linkage is employed when changing the valve from its first open state to a second open state.
