7616. Myer, V. H. March 26. Cylinders, attachments for compressing air.- In an air-pump of the kind that is attached to an internal-combustion engine cylinder for operation by the fluctuations of pressure therein, the air is drawn in through a trunk 33 attached to a piston 26 working in a cylinder 20 and compressed in the annular space A between the trunk and cylinder. The piston is formed with a chamber 32 which communicates with the trunk by way of a spring-pressed valve 9 and with the space A by way of a flap valve 11. During the suction stroke, both valves are open, so that air is supplied from the trunk to the engine cylinder as well as to the annular space A. Both strokes are cushioned, the downward stroke by a projection on the piston entering a recess 40, and the upward stroke by causing the piston to overrun the discharge port 12. The pump is provided with a handle 25.
