Abstract
A compressible fluid powered device includes a dose chamber. An inlet supplies pressurised fluid to the dose chamber. An outlet for releases pressurised fluid from the dose chamber. A moveable divider divides the dose chamber into a primary space and a secondary space, movement of the divider expanding one space at the expense of the other. At least one flow pathway from one space to the other, which collectively allow gas to flow in both directions past the divider and pressure to equalise across the divider, the flow pathway being much more limited than the outlet.

A compressible fluid powered device comprising:
- a dose chamber,
- a moveable divider dividing the dose chamber into a primary space and a secondary space, movement of the divider expanding one space at the expense of the other,
- an inlet for supplying pressurised fluid to the primary space of the dose chamber, an outlet for releasing pressurised fluid from the primary space of the dose chamber, and
- at least one flow pathway from one space to the other, which collectively allow gas to flow in both directions past the divider and pressure to equalise across the divider, the flow pathway being much more limited than the outlet.
