ABSTRACT:
A compressor having an electromagnetically actuated valve is disclosed. The movement of the compressor's piston is controlled by an electromagnetically actuated valve. The valve includes an electromagnetic element having a core and a coil, and an armature. The core has a surface and an opening at the surface extending through the core. The surface also includes a continuous channel extending around the opening. The channel has a top portion of frustroconical cross-section and a bottom portion. The coil is disposed in the bottom portion. The armature element has a raised portion dimensioned to be received within the top portion of the channel. The valve shaft is disposed within the opening of the electromagnetic element and is connected to the armature. The compressor piston is connected to one end of the shaft. A support spring is disposed within the opening of the electromagnetic element, and extends from the retaining bar to the upper surface of the cylinder. Two lower springs extend from the armature element to a lower support surface. The springs bias the armature in a normally spaced apart relationship from the electromagnetic element. Therefore, applying current to the coil in the electromagnetic element causes the piston to move upward, and interrupting the current to the coil causes the piston to move downward.
