The air which is compressed and stored in a compression chamber in the air-pressure weapon acts in the sense of increasing the retaining force on the valve head of a valve which connects the compression chamber to the barrel of the air-pressure weapon. When the trigger is operated, a spring-loaded firing element strikes the valve stem and opens the valve. In order to reduce the firing energy required, the valve stem is loaded by spring elements against the valve retaining force during or after the compression process. The loading is effected by the closing movement of the breech element, which acts on the spring elements via a control cam and prestresses them. The prestressing of the spring elements and of the valve stem against the valve retaining force reduces the necessary impact energy of the firing element and thus also the vibration of the weapon during firing. This results in a significant improvement in the firing accuracy.
