Title: Improvements in piston pumps, in particular for feeding fuel to internal combustion engines
IPC: F02M41/12
Filed: 1956-12-21
Abstract: 845,892. Fuel injection pumps. PRECISION MECHANIQUE. Dec. 21, 1956 [Dec. 23, 1955; May 25, 1956], No. 38959/56. Class 102(1). [Also in Group XXIX] A fuel injection pump comprises a pump piston 1 Fig. 1, driven from the engine which delivers fuel through conduit 3, non-return valve 5 and conduit 4 to the engine cylinder, the end of the effective stroke of the piston being controlled in the normal way by a groove 9 on the piston. The conduit 3 also leads by a conduit 32 to a valve chamber 14 housing a spring loaded valve member 13 having an axial passage 20 which opens at the upper end into a groove 24 and at its lower end into a groove 22 of variable depth. A piston 15 secured to the pump piston 1 reciprocates in a cylinder 16 and pumps liquid through conduit 17 to a chamber 23 and then through the variable groove 22 to the axial passage 20. By rotation of the valve member 13 the variable groove 22 provides an adjustable throttle for the flow of liquid to the axial passage 20. As the speed of the engine and hence the pump increases the liquid delivered by piston 15 causes the valve 13 to rise on each stroke of the piston and the groove 31 in the valve connects the conduit 32, leading from the delivery passage 3, to a by pass 33 thus providing a control of the quantity of fuel injected in accordance with engine speed. The valve 13 may be provided with a groove connecting the conduits 32, 33 in a certain angular position of the valve as a safety precaution when the engine is stopped. The liquid delivered by the pump 15 may be led to passages in the top of the valve. The invention may also be applied to an injection pump which feeds to more than one cylinder in which the piston 1 reciprocates and rotates and is provided with a groove communicating in turn with each outlet as in Figs. 9 and 11, (not shown), in this case the valve may have suitable passages which lead to grooves on the piston for determing the effective stroke. In the embodiment shown in Fig. 15 where the piston 1 reciprocates and rotates and delivers to the cylinders through a plurality of outlets 4, the valve member 13 is provided with a recess 63 having an inclined edge 64 so that by rotation of the valve 13 the distance h through which the valve must move to connect the conduits 32 and 33 may be varied. Specification 669,762 is referred to.

Abstract: 810,769. Ships with air cushions between hull bottom and the water. GRAM, K. F. Dec. 20, 1957 [Dec. 27, 1956], No. 39669/57. Class 113. In a ship having an air cushion 2 beneath its bottom 1 for reducing friction during forward movement of the ship, the air cushion is connected (by ducts 3, 5) at its ends into a closed circuit. A pump or blower 4 is provided for importing to the air in the cushion a velocity longitudinally of the ship. Air losses are made up from the atmosphere by a small compressor 7 delivering to a pipe 6 leading to the duct 3. The capacity of the pump or blower 4 may be adjusted automatically in dependence on the speed of the ship. The longitudinal velocity of the air in the cushion assists in stabilising the air cushion during moderate rolling but with large angles of roll air will escape at the sides and this can be avoided by providing the ship with means (such as blowers or anti-rolling tanks) for moving the air in the air cushion during rolling transversely of the ship with a periodically changing velocity and direction. In Fig. 2 a small anti-rolling tank consisting of legs 10 and 11 is arranged on each side of the air cushion 2. The tanks and air cushion are connected by air ducts 12, 13, the latter including a regulating valve 14. The system is brought into operation by the rolling of the ship, the air velocity being controlled by adjustment of the valve 14. The time of oscillation of the water in the tanks is made substantially the same as the period of roll of the ship but phase-displaced in relation to the rolling. Similar arrangements may also be made for adjusting the air in the cushion during pitching.
