Abstract
A metal diaphragm impulse pump with no valves is disclosed. The pump may be used in an angular velocity sensor utilizing the Coriolis effect on a fluid jet. A magnetic core is mounted within an anvil and a drive coil is wound around the core. The drive coil may be driven sinusoidally and the diaphragm, which is mounted on the anvil responds with a vibratory motion in like manner. Sensing poles are provided in quadrature with the drive coils and may be used to sense the vibratory motion and thereby control the fluid flow.
