Abstract
The present invention provides an air compressor, characterized in that the piston head has a concave portion having a plurality of through holes therein and a reed piece having a smaller area than that of said concave portion is disposed in said concave portion, said reed piece having an opening in its center to allow a seizing member, respectively, which is seized on a top center of said piston head, for freely moving through said opening, and said seizing member having a confining portion to confine said reed piece within a predetermined space for moving so that said reed piece moves toward or away from said plurality of through holes by means of reciprocally moving said piston rod to improve the air compression efficiency while said air compressor is operating.
Claims8
An air compressor, comprising a crankcase, a cylinder, and a piston rod having a piston head, said piston rod moving in said crankcase in rotary motion while said piston head moving in said cylinder in linear motion for external air to enter said crankcase via an air inlet thereof and then an air cylinder and for said external air in said crankcase to be discharged from said air cylinder via an air outlet thereof;
- characterized in that
- said piston head has a concave portion having a plurality of through holes therein for air flow, a reed piece having a smaller area than that of said concave portion is disposed in said concave portion, said reed piece having an opening in its center to allow a seizing member being seized on a top center of said piston head, said seizing member having a confining portion larger than the opening of said reed piece so as to form a predetermined space for confining said reed piece freely moving toward or away from said plurality of through holes by means of reciprocally moving said piston rod while said air compressor is operating.
