Abstract
A magnetic snap-action directional control valve mechanism preferably for use with a fluid pressure actuated reciprocating motor or pump (28). A driven member, represented by a tie rod assembly (42) in the described preferred embodiment, is caused to reciprocate at the same frequency as the reciprocating motor (28) due to contact of the driven member by a sealing member within the motor as represented by a piston (36) in the described preferred embodiment. The driven member includes a magnetic area which magnetically interacts with another magnetic area on the valve core of the magnetic directional control valve, thus causing the valve core (19) to also reciprocate at the motor frequency. Due to the nature of the magnetic interaction between the magnetic areas, the valve core (19) reciprocates in a snap-action fashion.
