In a rotary sliding vane machine of the kind comprising a housing having a non-circular bore in which a rotor having a diametral axiallyextending slot slidably mounting a vane, is eccentrically and rotatably mounted with the rotor and vane ends in line contact with the housing, the non-circular bore is in the form of a spiral of Pascal defined by the locus of all points which are respectively spaced an equal distance from the inter-section points of secants drawn through a fixed point of a circle and whose Cartesian co-ordinates are where r is the radius of the said circle and k said distance and wherein 2r/k is of a value greater than zero and less than 1/3. The construction of the curve is shown in Fig.1, C is the circle, r its radius, O the fixed point, 1, 2, 3 the intersection points of secants S 1 , S 2 , S 3 . . . and k the equal distances from the intersection points. The invention may be applied to a pump, fluid-operated motor or an internal combustion engine. Operating as a pump, a housing (2), Fig.3 (not shown) having an inner surface (8') which is a spiral of Pascal of substantially circular contour houses an eccentric rotor (12) in line contact with the surface (8') between a suction port (22) and a discharge port (24). The rotor is formed with a diametral slot (14) slidably mounting a vane (20) whose end edges (20'), (20") are also in line contact with the surface (8'). Operating as an I.C. engine, two housings (46), (48), Fig. 6 (not shown) are arranged end-to-end with a central wall (44) therebetween. A rotor (50) with a slidable diametral vane (56), Fig. 7 (not shown) in the housing (46) compresses a charge of gaseous fuel-air mixture admitted through a port (68), which via passages (62b), (62b') in the rotor (50) and a transfer passage (60) in the wall (44) is transferred to the housing (48) through passages (64b), (64b'), Fig. 8 (not shown) in a rotor (52) rotatable in the housing (48) and fitted with a slidable diametral vane (55). The compressed mixture is ignited by a spark-plug (70), expanded in the housing (48) and finally exhausted through a port (72).

Title: Control systems for internal combustion engines
IPC: F02D1/10
Filed: 1962-11-20
Abstract: 978,138. Regulating I.C. engines. GES. FUR LINDE'S EISMASCHINEN A.G. Nov. 20, 1962 [Nov. 20, 1961], No. 43784/62. Heading F1B. [Also in Division G3] In an I.C. engine fuel injection pump control system, having centrifugally-movable elements 8, Fig. 2, connected to the pump adjusting element through a movable control member 3 spring-loaded by a main loading spring 23 effective above a predetermined low engine speed and by a supplementary spring 4, the loading of the main spring is adjustable to vary the engine speed, the supplementary spring is operative at speeds up to the predetermined speed to set the pump at maximum delivery and a lostmotion linkage 13, 14 is effective between the control member 3 and spring 23 only when the engine speed is below the predetermined speed. On starting, weights 8, governor sleeve 6 and control lever 3 are in the position shown in Fig. 2, and since pin 14 is not in contact with the lower wall of hole 13, spring 23 does not influence reaction lever 12 or control lever 3. With increasing speed, weights 8 are forced outwardly and move sleeve 6 to the right to pivot governor levers 11, reaction lever 12 and control lever 3 to reduce the rate of fuel injection. After the lower wall of hole 13 contacts pin 14, further movement compresses spring 23 between abutment 24 and the end of an adjustable sleeve 21, until a balanced state is achieved. Speed is increased by pivoting spindle 27 so that pin 26 forces sleeve 21 downwards to increase the bias loading of spring 23. With large speed reductions, shoulder 16 contacts a plate spring 18 which acts in opposition to spring 23 so that lever 3 takes up a position giving an increased fuel injection rate. Spindle 27 is pivoted so that adjusting sleeve 19 is moved upwardly to set lever 3 to zero delivery thus stopping the engine. A stop pin (not shown on Fig. 2) limits movement of sleeves 19 and 21. In a modification spring 4 is replaced by a torsional coil spring attached to shaft 5.
