At the bottom of the stroke the intake valve closes and air is trapped in the cylinder. The air is then compressed in the cylinder and pushed through the discharge valve on the up stroke of the piston. Total compression, from atmospheric pressure to the final discharge pressure, is accomplished in one stroke of the piston. Assist Ingeniería S.A.S. Cra. 69B No 97ª-20, Bogotá Colombia.
