Abstract:
1. Loss reduction apparatus for a fluid transfer system, characterised in that the loss reduction apparatus comprises: a fluid device which defines: a first fluid path along which a greater part of a fluid flows in a first condition, and a second fluid path along which a greater part of the fluid flows in a second condition, the apparatus being arranged so that when a leak occurs at a location in the system, the leak causes a relative reduction in fluid pressure at the location which moves the device from the first condition to the second condition, the fluid device including a first device, which is a bistable fluidic device, the first device having a control means that operates to divert the flow from the first path to the second path when the leak occurs, the control means including control passages, along which control fluid flows are communicated which operate to divert the fluid flow, the reduction in pressure at the leak location changes the fluid flows along the control passages to divert the fluid flow; and a second device, which is a vortex device.
