Abstract
PURPOSE: To prevent overload of a motor without installing an unloader, by allowing a spring to be interposed between a piston and a connection rod of a small piston type air compressor and releasing abnormal pressure from the slit formed due to the compression of a spring.
CONSTITUTION: A piston 5 is connected with a connecting rod 3 by means of the spring force of a spring 7 and a spherical seat 6, and air tightness is kept by spherical surface. Arbitrary number of intake holes 10 are formed on the piston 5, and an intake valve 11 made of elastic thin plate is installed on the compression side of to hole. When the elasticity applied onto the piston 5 by the spring 7 is set P, a prescribed compression force is set (p), and the area of the piston is set A, then operation is performed with the relation p×A≤P. When the compression force (p) is above the prescribed value p', p'×A>P is formed, and the spring 7 is compressed, and over the contact spherical surface of the spherical seat 6, a slit 17 is formed, and pressure is released, and the overload of a motor can be prevented.
