Title: Improved control mechanism for supercharged internal combustion engines
IPC: F02D9/00
Filed: 1945-04-11
Abstract: 600,934. Fluid-pressure servomotor-control systems. GENEBAL MOTORS CORPORTION. April 11, 1945, No. 8998. Convention date, April 26, 1944. [Class 135] [Also in Group XXVII] A control mechanism for internal-combustion engines comprises a manually-operable member for moving the intake throttle and for selecting by means of a cam a boost pressure to be maintained in the engine intake manifold, and a device responsive to pressure in the manifold such that divergencies from the selected pressure control the throttle valve through a servomotor so as to restore the selected pressure, and means independent of the manual member for modifying the action of the pressure selector cam on the servomotor under certain conditions of operation to prevent a pressure in the manifold sufficiently high to cause detonation. As applied to an engine having a main supercharger directly driven from the engine and an auxiliary variable-speed supercharger, the boost pressure is selected by a cam 40, operated by a lever 20 from the pilots' throttle control lever, which adjusts a floating lever 45 connected to capsules 58, 50 and operating the valve 30 of a servomotor 24, controlling the throttle valve 11, the action of the cam being modified above a certain altitude when in its high boost pressure position by a capsule-controlled stop rod 70 which moves the lever 45 to the right and reduces the boost pressure to prevent detonation. Capsules 58, 50 are spring-loaded, capsule 58 being evacuated and the interior of capsule 50 being exposed to induction pipe pressure, fluctionations in which expand or contract the capsule and alter the position of lever 45, thereby opening the servo valve 30 and operating the servomotor to open or close the throttle valve 11 and maintain the selected pressure. The evacuated capsule 77 controlling the stop rod 70 is exposed to intake air pressure through duct 75. In a modification, Fig. 4, the stop rod 90 is controlled by the temperature on the outlet side of the auxiliary supercharger, which temperature rises with increasing altitude. A finned tube 94 in the engine intake manifold 93 is connected by a pipe 95a to a bellows 101 controlling the rod 90, the whole assembly being filled with a liquid of desired coefficient of expansion. When the induction temperature exceeds a certain value, the bellows 101 expands, moving rod 90 to the right and reducing the boost pressure as before. Initial adjustment of the rod 90 is obtained by means of screw 115, Fig. 5, carrying an eccentrically situated pin 111 engaging in groove 110 in the side of the casing 98. In an engine having only one directly driven supercharger, in which danger of detonation occurs at low altitudes, a similar construction to that of Fig. 4 is used, but the rod 90 holds lever 45 off the cam 40 at low altitudes and it is moved to the left to allow increased boost pressures at higher altitudes.

Abstract: 151,668. Dawson, Sir A. T., and Buckham, Sir G. T. April 9, 1919. Loading-appliances.-Consists in arrangements of rearwardly-inclined hoists adapted to raise projectiles to a non-turret gun from a stationary chamber beneath the gun platform. The hoist and its casing rotate with the gun in training, and the projectile is tilted as it arrives at the top of the hoist into a position suitable for transfer on to a waiting tray, which may be fixed to the platform, or to the gun cradle. In the former case, the projectile is lifted by hand from the waiting tray to the usual swinging loading-tray carried by the cradle. Stop devices are provided on the waiting tray to ensure regular functioning of the whole arrangement. A hoist delivering on to a non-elevating waiting tray is shown in Fig. 1. The lower end of the hoist B is located in a non-rotating chamber A, while the upper end and the waiting tray E are fixed to the rotating platform P. The projectile is raised, nose downwards, in a tray C by a cable C<x> attached to a stirrup on the lower end of the tray and operated by a crank handle C<2x>, or by an auxiliarv crank C<2xx> in the chamber A. The tray is guided by rollers C', C<5> running in guides B<1>, B<2>, the guide B<2> being curved at the top so that the tray C arrives opposite the waiting tray in the position shown in Fig. 8. A stop G on the waiting tray prevents transfer of a projectile thereto from the hoist tray C when a projectile is already on the tray E. When the waiting tray is carried by the gun cradle, the hoist tray is raised until the rollers C<5> engage recesses in the waiting tray and form pivots about which the tray C is tilted into alinement with the waiting tray. Stops on the waiting tray prevent the alinement of the trays while a projectile is awaiting transfer to the gun breech; other stops are provided to prevent rearward sliding of the projectile on the waiting tray until the loading tray F is alined with the waiting tray, and to prevent forward sliding of the projectile when the ship rolls.

Abstract: 115,529. Hutchinson, E. June 23, 1917. Spray carburettors.-Air channels i, Fig. 3, are provided adjacent fuel orifices or an elongated fuel orifice e which discharge into a straightthrough passage a, Fig. 1, controlled by a transversely adjustable throttle valve b with which the orifices are in alinement. The fuel reaches the orifices e through a nozzle g and fuel chamber f which may be in communication with the atmosphere through a controlled conduit q. A restricted passage h may be provided between the nozzle g and chamber f. One or more fuel orifices j may be provided on the air-inlet side of the airchannels i. In modifications, the fuel orifices may be arranged radially with sector-shaped air channels between them, or they may be arranged around three sides of a square air channel. In the modification shown in Fig. 6, the intermediate fuel chamber is not open to the atmosphere and is in two parts r, s fed through inlets t, u. With any of the above constructions, fuel is extracted from only those orifices near the mixture outlet for nearly closed positions of the throttle valve, and uniformity in the composition of the mixture is maintained since the number of fuel orifices in action is dependent on the extent of throttle opening. The main air supply may be cut off to facilitate starting.
