The acting zone (73) has a noncircular spacing groove (74), a neck (734), and a second bending section (75). The head (21) includes a piston rod (5) having a cavity (50), an air conduit (52), a column (53), and a spring (54). The air stop sheet (7) is forced by the spring (54) to locate in the acting zone (73) backing the cylinder (13) and a plane of a top of the head (21) at an open angle θ1 .

Abstract: An improved air compressor includes a cylinder (2) fitted with a piston body (14), a main frame (11) for mounting a motor (12), and an air storage container (3). The cylinder (2) defines a plurality of exit holes (4, 5, 6)(43, 53, 63) regulated by a control mechanism including a resilient sheet (7)(8)(9) having a root (70)(80)(90) and a plurality branches (72, 73, 74)(82, 83, 84)(92, 93, 94) corresponding to the exit holes. The root and branches of the resilient sheet are individually attached to a top wall (21) of the cylinder (2) at separate points, so that each of the branches can be individually moved by the compressed air produced in the cylinder (2) to open or close the corresponding exit hole without affecting movements of the other branches, so that the piston body (14) can conduct reciprocating motion more smoothly, and thus the performance of the air compressor can be increased.

Abstract: An air compressor is disclosed, which can keep the pressure of air supply less than a safety pressure without using a safety valve, so that a tire can be inflated without exceeding a safety pressure thereof. One feature of the air compressor is that: when the piston body, which conducts reciprocating motion in the cylinder, reaches top dead center, a space is existed between the head of the piston body and the top wall of the cylinder. Another feature of the air compressor is that: an adjusting bolt is used to adjust the volume of the auxiliary air chamber to change the maximum permissible output pressure of the air compressor to suit an object. As such, the air compressor does not require a mechanical safety valve to release air for limiting the pressure of air supply. The air compressor can protect a tire from over-inflation and save the manufacturing cost.

Abstract: An air compressor is disclosed, which provides compressed air having a pressure less than a safety pressure without using a safety valve, so that a tire can be inflated without exceeding a safety pressure thereof. One feature of the air compressor is that a tube is formed integrally with the air storage container and on the cylinder, wherein the tube defines therein an auxiliary air chamber communicating with the inner space of the cylinder but not communicating with the air storage container. When the piston body reaches top dead center, the head of the piston body almost contacts the top wall of the cylinder, whereby part of the compressed air may flow into the auxiliary air chamber, so that the piston body can conduct downward strokes more smoothly, and the compressed air can be prevented from exceeding a safety pressure set for an object to be inflated.
