ABSTRACT:
A reciprocating armature motor for electrically driving equipment such as a piston pump for a paint spray gun or a diaphragm compressor characterized by a stator having a solenoid, an armature pivotally mounted at one end to the stator and having a second end acting upon a member of the equipment to be actuated to move the member back and forth along a path when the armature moves relative to the stator with a reciprocating motion and an arrangement for controlling the reciprocating motor of the armature including a coupling link forming a positive link between the armature and a stationary element which coupling link moves depending on the reciprocating motion of the armature. In one embodiment, the coupling link is composed of a pair of pivotally connected arms forming an articulated link which interconnect the armature to the stationary element and coact with a stop to limit the movement of the armature toward the stator. In another embodiment, the coupling link is formed by a cam disk mounted for rotation on the stator and a torsion spring having one end connected to the armature and the other end connected to the link to hold the armature in contact with the cam disk.
