Abstract

An improved air compressor includes a cylinder with a piston body and an air storage container. The air storage container can be detachably mounted to the cylinder to define a primary air chamber, and an auxiliary air chamber which can reduce the motion resistance of the piston body, so that the piston body can conduct reciprocating motion in the cylinder more smoothly. Furthermore, the cylinder has an open bottom that is divided into two halves according to a central vertical line (Y) of the cylinder, wherein one half of the open bottom is horizontal while the other half of the open bottom is slanted. When the piston body reaches the bottom dead center, the head of the piston body will be entirely within the cylinder and thus keep air-tight with the cylinder. Therefore, the performance of compressing air and the operational safety can be increased.

Dependent claims

In an air compressor including a main frame, a motor, and a cylinder fitted with a piston body, the motor and the cylinder being provided at the main frame, the motor capable of driving the piston to conduct reciprocating motion in the cylinder to produce compressed air, which is transferred to an air storage container;

wherein the improvement comprises:
the air storage container, being made separately from the cylinder, has a closed top, a surrounding wall extending from the closed top to define an inner space that terminates at an open bottom, the inner space serves as a primary air chamber for storing the compressed air produced in the cylinder;
a tubular connection portion is formed on the top wall of the cylinder, the tubular connection portion defines therein an exit hole communicating with an inner space of the cylinder, the space of the exit hole serves as an auxiliary air chamber for storing additional compressed air.
