Abstract

698,629. Fluid-pressure engine valve gear. BLAW KNOX, Ltd. Dec. 5, 1951 [Oct. 9, 1950], No. 24621/50. Class 122(ii) [Also in Group XXVIII] In a pump for concrete, the pump cylinder 1 has rotary oscillating inlet and outlet valves 9, 5 respectively which are geared together by pinions 8, 12 actuated by a rack 41 secured to the pistons 39, 40 of fluid pressure motors 35, 37. The pump piston 2 is actuated by a fluid pressure motor 15 the piston rod of which actuates a piston valve 27 to connect alternately the motors 35, 37 to the fluid pressure supply line 33 and exhaust. The rack 41 is connected by a lever 43 to a piston valve 19 that controls the pressure fluid and exhaust connections to the motor 15. In an alternative arrangement, each pump valve is actuated by a fluid pressure motor and the supply of pressure fluid is such that one motor completes its stroke before its piston opens a port to permit pressure fluid to flow to the other motor; the motor actuating the outlet valve is connected to the piston valve 19.
