A lock for the loading and/or discharging of, in particular, not easily flowing, adhering bulk materials into or out of a pressurized or vacuum chamber through a discharge opening of a discharge housing, the operating chamber being adjoined by a housing having an inlet connector. Guided in this housing is a piston which transports the bulk material from the inlet connector to the discharge housing. During this procedure, the discharge housing is closed off in relation to the housing by an openable valve.
