Abstract: A closure of a tank of a motor vehicle for closing a filler neck gas- and fluid-tight, having a closure fastened to a flap, the flap being fastened to a vehicle body of the motor vehicle such that it is movable into an open or closed position, the closure including a seal, which causes the closure to close against the filler neck. The tank closure should be easy for a user to handle and have a relatively simple design and be economical to manufacture. This is achieved in that the seal is electromechanically or pneumatically adjustable with the aid of an actuator.

Abstract: A pedal emulator (20, 100) is provided. The pedal emulator includes an emulator piston (28, 102) coupled to a damper (46, D1) that is contained within a housing (22, 104). The damper is surrounded by first (34, S1) and second (38, S2) springs that are carried by a lower spring seat (114), the lower spring seat being upwardly biased by a third spring (S3), for example a wave spring. The first and second springs and the third spring cooperate to provide a counter-force that is tailored to the desired feel of the pedal. First and second sensors measure travel (72,74) and force in response to downward compression of the emulator piston, and the damper provides hysteresis upon return travel of the emulator piston.
