Abstract

225,813. Eloy, F. Dec. 8, 1923, [Convention date]. F l u i d - actuated gears.-In percussive hammers and like apparatus, the inlet and exhaust of the two ends of the cylinder are controlled by separate valve members which are held in con. tact by fluid pressure and which work together. The valve members 7, 8 are provided with actuating and exhaust, controlling-heads 22, 23, 21, 24 respectively, and inlet controlling-ends 25, 26. The member 7 has a projection 27 which is a sliding fit in the wall 6 and engages the member 8. When the piston 2 moving downward under the pressure fluid supplied through ports 9, 10 passes the port 14, the fluid enters the chamber 4 and acts upon the head 22 the pressure upon which together with the supply pressure on head 24 overcomes the supply pressure on head 21 and reverses the valve. The compression at the bottom of the cylinder on the end 26 also assists the reversal. The upper cylinder end then exhausts through ports 13, 17, and the. lower admission and exhaust ports 12, 15 respectively are opened and closed. The part 27 may be a separate member.
