PNEUMATIC MOTOR WITH AIR DISTRIBUTION BATH

摘要

PURPOSE: Provided is a pneumatic motor with an air distribution bath which uses a port switch type air distribution bath to supply compressed air with high pressure so that it minimizes the loss of air in supplying compressed air. CONSTITUTION: The pneumatic motor with the air distribution bath comprises the parts of: a distribution bath body(11) which forms more than one insertion holes and a circulation hole; an operation hole which is connected to a first channel; a port switch part(20) which is placed in the operation hole to operate; a cylinder block(30) which forms a second channel to connect to the first channel with including a cylinder room(31); a drive part(40) which places more than three connecting loads(43) in an eccentric axis(42) of a crank axis(41) and forms a piston(44) at one edge; a switch(50) which is fixed at the outer circumference of the crank axis to operate a switch pin(21) selectively; and a first and a second cover(60, 60a) which are fixed at both sides of the distribution bath body and placed at both edges of the crank axis.
