Title: A hydraulically operated throttle control for an internal combustion engine
IPC: F02D11/06
Filed: 1961-11-06
Abstract: 1,010,150. Telemotor; regulating. V. D. ROOSA. Nov. 6, 1961, No. 39694/61. Headings F1B and F1P. An I.C. engine throttle control device comprises a master cylinder 82, Fig. 2, having a slidable plunger 98, 110,116, and connected by a hydraulic conduit 10, Fig. 5 to a slave cylinder 40 having a thrust member slidable therein and operatively connected to the throttle control lever 24 and having a check valve 56 which is open when the plunger moves to the idling position to allow admission of make up fluid to the system. The source of fluid comprises the petrol pump 6 at to 2 to 3 p.s.i. above atmospheric. The valve 56 is biased by a spring 50 within an axial bore 52 of the thrust member 22 the effective stroke of which is varied by screw adjustment of the slave cylinder 40 within a tapped opening 16 of the pump casing 18. The inner end of the master plunger slides through an annular piston 116 until a shoulder 112 abuts a ring 124 behind the said piston 116 whereon the effective area of the plunger is increased. Air is bled from the master cylinder through recesses 114 and past a flat 136 on the inner end 110 of the plunger a clearance space 140 and past a check valve 148 to a conduit 144 leading back to the pump casing 18. The conduit 10 may include a solenoid-opened one-way valve 150, Fig. 7 (not shown) which when closed prevents flow of fluid from the slave to the master cylinder and thus allows the throttle control lever to be held at a desired setting until such time as the valve is opened by the solenoid. The throttle lever 24 controls the output of the fuel-pump 6 by positioning a spring seat 28 slidable on a guide rod 30 and engaged by one end of a governor spring 32. The opposite end of spring 32 is engaged by the outer end of a governor arms 34 which is thus urged counterclockwise responsive to engine speed. The seat 28 is connected by a rod 36 to the fuel pump metering valve 38. Specification 839,308 is referred to.

(Fig. 1) comprises production tubing D, packers R, S, T . . . separating the zones, and a flow regulator 12, 12a, 12b . . . in the tubing at each zone to pass fluid from the associated zone to the interior of the tubing, each regulator including a flow restrictor 14 to reduce the pressure of the fluid flowing from the associated zone. Opposite each zone the tubing has a port 10 closed by a valve sleeve 21 held in its closed position by latches 30 (Fig. 3a). The sleeve is moved to the open position shown in Figs. 3a, 3b by a flow regulator which has dogs 40, 48. When moved to its open position the sleeve is connected to the regulator by the latches and the regulator is connected to the tubing by the dogs so that the sleeve is held in its open position. With a sleeve 21 in its open position, fluid from the associated zone passes through perforations M and ports 10, 57 into passage 58 in a regulator port 54, and then past non-return valve 13 through ports 78 of regulator valve 69, orifice 14, and ports 62 into the tubing. Regulator valve 69 moves against spring 72 to control the ports 62 and maintains a constant pressure differential across orifice 14. Initially the packers are set about the tubing and the sleeves 21 are closed. A regulator is run into the lower sleeve 21 on a tool (100). After locking the regulator to the tubing and setting the sleeve to its open position, the tool is removed and the other regulators are positioned in the tubing in turn. Starting with the upper one the regulators are removed by a fishing tool from the tubing and during this removal the respective sleeves are set to their closed positions.
