Abstract

A pneumatic motor in which a piston is reciprocatingly movable in a cooperating cylinder equipped with a cylinder head, the piston head is provided with a coaxial cylindrical extension directed towards the cylinder head, whereby the total effective area of the piston is the sum of the area of the piston. the circular part defined by the end of the cylindrical extension remote from the head of the piston, and the area of the annular part defined by the union of the cylindrical extension with the piston head, which is formed put a bore to receive the extension cylindrical, the annular part of the piston in conjunction with its cooperating cylinder and the cylinder head defines a chamber, another chamber communicates with the circular part of the piston a seal is operatively arranged between the cylindrical extension and the bore so that the two chambers will be insulated one of the other during the limited axial movement of the piston in which the cylindrical extension cooperates with the joint hermetic, one of said chambers is adapted to receive a supply of gas under pressure to act on the respective part of the piston to drive the piston away from the cylinder head, means arranged to prevent the admission of gas into the other of said chambers in a manner that the initial movement of the piston away from the cylinder head will produce a reduction of the gas pressure in said other chamber which resists the further movement of the piston away from the cylinder head until the joint between the cylindrical extension and the bore is interrupted so that the pressure acting in said first chamber is applied to said other chamber to produce a sharp working stroke of the piston away from the cylinder head, escape means to release the gas pressure in said chambers after the initiation of said working stroke, means adapted to produce a return stroke of the piston to the cylinder head after the work career has has been completed, and means for releasing gas from said other chamber after the joint has isolated the two chambers during the last part of the return stroke.
