1. A hydraulic fitting (10) for a hydraulic transmitter system (100) having a housing (12) in which a fluid reservoir (16), a pressure chamber (20) which is fluidically connected to the fluid reservoir (16) and a venting bore (22, 22′) which connects the pressure chamber (20) to a housing surroundings are configured,
wherein the venting bore (22, 22′) can be closed during operation and can be opened to produce a venting position (V), said hydraulic fitting (10) also having an additional fluid connection between the fluid reservoir (16) and the pressure chamber (20) which is interrupted during operation,
wherein the additional fluid connection between the fluid reservoir (16) and the pressure chamber (20) is a connecting passage (26) between the fluid reservoir (16) and the pressure chamber (20), said hydraulic fitting (10) comprising a closure element (24, 46) that can be actuated from outside the housing (12) between a closed position (III) interrupting the connecting passage (26) and a rapid venting position ((V) opening the connecting passage (26), and said connecting passage (26) can be temporarily opened by moving the closure member (24, 46) to the rapid venting position (IV) to permit rapid venting while the venting bore (22) remains closed.
