Beschreibung
Zusammenfassung:	A pneumatic circuit for a pneumatic drive apparatus is disclosed. The pneumatic circuit includes a reservoir, a pump, and first, second and third valves. The first valve selectively provides a fluid connection between an inlet of the pump and the reservoir. The second valve selectively provides a fluid connection between an outlet of the pump and the reservoir. The third valve selectively provides a fluid connection between the reservoir and an actuation port. The pneumatic circuit is configured such that the first and second valves can selectively pressurise the reservoir, and such that the third valve can selectively communicate pressure from the reservoir to the actuation port.
