ABSTRACT:
An oscillating pump (10) includes a housing (11) which carries the components thereof. These components include an electromagnetic coil (24) surrounding an armature (23) carried by an impeller (12) which is positioned longitudinally between an inlet area (16) and an outlet area (17) of the pump (10). The armature (23) moves longitudinally upon activation of the coil (24) to the point of the greatest magnetic force generated by the coil (24). The impeller (12) includes a pair of bellows (19, 20) and carries a valve (13). The bellows (19, 20) define an inlet chamber (21) and a discharge chamber (22). Another valve (15) is carried by the housing adjacent to the discharge chamber (16). Upon activation of the coil (24) the valve (13) forces fluid in the discharge chamber (22) through the valve (15) and allows fluid to pass from the inlet chamber (21) to the discharge chamber (22) upon deactivation of the coil (24). The return force to move armature (23) in the opposite longitudinal direction is solely provided by the bellows (19, 20).
