Abstract
A housing 10 defining a duct 11 for fluid flow contains a cylinder arrangement 18-20 mounted in or at an outlet end of the duct. An input piston 30 is exposed to the fluid flow through the duct and an obturator member 21 is mounted in the duct 11 and arranged to periodically close the duct downstream of the input piston 30 such that the body of fluid flowing through the duct applies an increased pressure to the input piston. Resulting movement of the input piston can be used to directly provide mechanical power, generate electricity, or provide compression of a volatile fluid which, when ignited, provides thrust through rapid exit of combustion products.
