Abstract: 1485297 Driving I C engine fuel-injection pumps DAIMLER-BENZ AG 29 Nov 1974 [7 Dec 1973] 51862/74 Heading F1B In a reciprocating-piston in-line engine having its valve and fuel-injection timing gear located at the flywheel-end in a housing 2, provision is made for mounting the fuel-injection pump 11 in alternative positions depending on the orientation and location of the engine in a vehicle so that it is accessible for maintenance. If the engine is to be mounted under the floor of the vehicle with its cylinders horizontal, then the pump 11 is mounted in the position shown and is driven by the injectiontiming gear-wheel 9 via at least one idler gear-wheel 13. If the engine is mounted with its cylinders vertical and/or at the rear of the vehicle, then the pump 11 is mounted in a different position with its axis 10 located at 10' and is driven directly by the gear-wheel 9.

Title: Fuel injection valve
IPC: F02M61/04
Filed: 1968-11-04
Abstract: 1,243,034. 243, 034. Fuel injectors. CATERPILLAR TRACTOR CO. Nov.4, 1968 [Nov. 6, 1967], No.52082/68. Heading F1B. In a fuel injection valve for an I. C. engine, fuel from a line 16 is delivered between valve case 12 and sleeve 26 to a valve chamber 52 via passages 30, 32, annular groove 34, longitudinal blind grooves 36, the clearance between the sleeve 26 and the surrounding case 12, and reversed longitudinal blind grooves 40. The clearance forms a filtering passageway for the fuel. A predetermined fuel pressure in the chamber 52 opens a valve 56 against the action of a spring 66 until an enlarged valve stem portion 60 abuts a stop 48, to allow fuel to flow through orifices 24 to the engine combustion chamber. The coils of spring 66 may be arranged to abut one another at the required degree of valve opening, thereby eliminating the need for the stop 48. The stem portion 60 is slidingly received in a mounting collar 62 having a spherical surface 68 sealingly co-operating with a conical surface 70 on the sleeve 26. During opening of the valve some fuel leaks between the stem portion 60 and collar 62 into a chamber 28. The leakage returns to the chamber 52 when the pressure therein falls to a relatively low value. The sleeve 26 may be secured in the case 12 by welding or press-fitting, or it may be screwed therein to provide adjustability of the compression of the spring 66. Injector tip 20 may be integral with the case 12 or swaged thereto. Spring retainer 64 may be integral with the valve.

Abstract: 1368173 Tailgates DIESEL EQUIPMENT Ltd 22 Nov 1972 [25 Nov 1971] 54058/72 Heading B7B In a powered tailgate for a vehicle comprising a tailgate platform which is pivoted at its inner edge to slide members 16 which may be raised or lowered, the platform has an inner part 14b and an outer part 14a which are hinged together. In a preferred embodiment, Fig. 1, box 12 contains an hydraulic mechanical system for raising or lowering the tailgate, the members 16 being slidable in posts 10. Torsion bars 22 bias the platform into the vertical position. In the folded position hooks 26, Fig. 3, engage in brackets 28 welded to the posts 10. Before pivoting outer part 14a about hinges 20, locking bars 30 are freed from channel members 32, 34 by interconnecting levers 36, 38, the latter being fixed rigidly to transverse rod 24 which has a similar lever mechanism mounted at its other end. A stud (48), Fig. 2 (not shown) fixed to part 14a is engaged in a notch 50 in lever 36 to lock the platform in the folded position. Rod 24 also carries a rigidly attached lever 52 which swings under a stop member 54 on post 10. As a safety measure, lever 52 with lever 64 is also used to render inoperative a control lever 60 of the hydraulic drive system 12-when the platform is folded. Fig. 4 shows the platform parts connected by a chain 70 which pulls against two leaf springs 72, the bias of which assist in the unfolding of the platform. Alternatively, Fig. 6, a pair of cables 74 exert bias in coil springs 76 when the platform is folded. In a modification, Fig. 7, the parts 14a, 14b have overlapping flanges 110a, 110b hinged by pivot pins 114, the flange 110a bearing against a channel member (115), Fig. 10 (not shown) to prevent inward folding of the parts 14a, 14b. Arms 116 the upper ends of which are connected to slide members 16 by chains 120 are pivotally connected by pins 118 to outer portion 14a and apply an opening moment about stops 117 to retain the platform in the unfolded horizontal position. Flanges 124 each have a slot 125 receiving a latch pin 128 of the portion 14a when the tailgate is lowered by the hydraulic drive in the folded position. A latch 130 is then manually moved to lock in the pin 128. A mechanism is provided, Fig. 11 (not shown), which does not allow valve (146) of the hydraulic drive to be opened by control rod 154 when the latch pin 128 is locked in.

A device for dispensing measured quantities of granular material comprises at least one pair of pivotally mounted, open-sided containers 2a, 2b arranged on each side of a common closure wall 4 and a stop member 9a, 9b, associated with each container and adapted, upon relative motion, to abut against the container in an end position such that the container is pivoted away from the wall whilst the other container is urged into sealing engagement with the wall to form a closed measuring chamber. The containers are mounted on shaft 5 and normally held against the wall 4 (also on the shaft) by springs 8 mounted on a frame 6, having a knifeedged bar 7 engaging in notches formed in the containers. In operation, with the device in the position shown, material flows from a hopper 1 into the container 2a until it stops when the level of the material reaches the outlet la in the hopper. Upon rotation of the shaft, the container abuts the stop 9a so that the container is lifted away from the wall 4 and thereby allows the material to fall through an outlet funnel 10. The capacity of the containers may be varied by raising or lowering the hopper or the containers in relation to the top edge of the wall. In order to enable the outlet end la of the hopper, when in a low position, to clear the top edge of the wall, a cam (14, Fig. 3) is secured to the frame 6 so that as the containers move the cam co-operates with a roller (15) on the hopper thereby raising the latter.
