Abstract
A turbo pump vent assembly and method are disclosed. The turbo pump vent assembly comprises: a primary manual actuator operable to deliver an initial volume of air to a turbo pump; and a secondary manual actuator operable to deliver a secondary volume of air to the turbo pump, wherein the secondary volume of air is greater than the initial volume of air. In this way, an uncomplex and reliable vent is provided which can deliver initial volumes of air to slow the turbo pump initially. Thereafter, the secondary volume of air may be delivered to slow the turbo pump more rapidly than is possible just using further initial volumes of air. Having an apparatus which can deliver differing volumes of air enables the turbo pump to be slowed safely and more quickly than is possible by delivering just the same sized volumes of air.
