Abstract
A pump wherein an armature (64) is reciprocated between an electromagnetic core (54) and a housing (48). A diaphragm (68) is responsive to movement of the armature (64) and cooperates with a body (10) to form a pumping chamber (80). Expansion of the pumping chamber (80) by spring (66) draws fluid through a valve (20) at a slow rate. Contraction of the pumping chamber (80) by electromagnetic attraction of armature (64) to core (54) expels fluid through valve (42).
