Fluid driven reciprocating linear motor
Abstract:
A reciprocating linear motor powered by one directional fluid flow is provided, having small external diameter, optimized for length, with few moving parts and effective seals, low mass and thus low inertia in direction changes. The motor provides reciprocating linear powered motion for use by attached equipment such as a pump, chisel, hammer, valve, or other machine requiring such power.
