Pressure vessel, in particular for accommodating a liquid such as a spray substance for a paint spray gun

摘要

The invention relates to a pressure vessel (1), in particular for accommodating a liquid such as a spray substance for a paint spray gun, having a pressure reservoir (2, 30) and a removable cover lid (3, 31) which can be clamped in a closed position, the pressure reservoir (2, 30) having a bearing collar on its lid-side margin and the cover lid (3, 31) having a lid margin allocated to the bearing collar, the cover lid (3, 31) being axially movable during the build up of a difference between reservoir internal and external pressure (positive pressure or vacuum), and a radial seal being provided which seals against the inner surface of the pressure reservoir (2, 30). In order to achieve safe manipulation of the pressure vessel, the invention proposes that actuation of a pressure discharge valve (49) arranged on the cover lid (31) be combined with locking or unlocking of the cover lid (31) on the pressure reservoir (30). <IMAGE>
