Abstract
A shower head, illustratively for a sanitary shower, including a shower head housing, a fluid inlet into the shower head housing, a shower jet outlet out of the shower head housing, a fluid duct within the shower head housing from the fluid inlet to the shower jet outlet, and an overpressure valve pressure-coupled to the fluid duct, including a movable valve body which, in case of an overpressure in the fluid duct, moves from a normal position to an overpressure position. The valve body is illustratively configured to be self-retaining in the overpressure position and returnable to the normal position by user operation, and/or the valve body acts position-dependent on a passage cross-section of the fluid duct, wherein the valve body reduces the passage cross-section in the overpressure position relative to the normal position.
