Title: Improvements in fluid actuated suspension devices for vehicles, aircraft and the like
IPC: B64C25/60
Filed: 1946-08-16
Abstract: 615,860. Hydro-pneumatic shock-absorbers. MARSTON, W. W. Aug. 16, 1946, No. 24371. [Class 108 (iii)] In a shock-absorbing suspension device for vehicles, aircraft, &c. of the kind in which a pair of relatively-slidable members connected respectively to the wheel mounting and to the vehicle frame, define two working spaces of variable volume each occupied by hydraulic fluid, each volume of the fluid being associated with its own volume of compressible fluid separated therefrom by movable means, flow of hydraulic fluid from one working space to the other is automatically permitted in accordance with a predetermined relative position of the members. In the construction shown, the piston 1 and cylinder 2 define two liquid spaces 17, 18. The space 17 is connected by a conduit 19 with the lower half 8 of a casing 5 containing an angular rubber compressed-air bag 10. The space 18 is connected by annular space between the cylinders 2, 3 and a conduit 26 with the upper half 7 of the casing 5 which contains an annular air bag 9. Liquid pressure on the bags 9, 10 is distributed by holes 28, 28<SP>1</SP>. Liquid damping of relative movement between the cylinder 2 and piston 1 occurs due to the restriction between the internal piston surface and the lower part of the conduit 19 which is tapered to provide a progressive action. A groove 29 in the wall of the cylinder 2 connects the spaces 17, 18 when the piston 1 is in its undeflected position.

Variable -speed and reversing epicyclic gearing suitable for motor-vehicles comprises stepped planet gears C meshing with a sun gear B secured to driving- shaft A, with a loose internallytoothed ring D, and with a sun gear 0 loose on a driven shaft H in line with the shaft A. A sleeve J sliding on a feather on the shaft H carries clutch teeth J' adapted to engage teeth 0<1> on the gear O. A second feathered sliding sleeve K has teeth K<1> adapted to engage teeth E' on the planet carrier E. A third like sleeve P has a friction cone L adapted to engage a cone on the member D, and has also teeth P<1> adapted to engage teeth D<2> on the member D. A first or lowest speed is obtained when the ring D is held against rotation and the shaft H is clutched to the carrier E by the sleeve K. A second speed is obtained by holding the carrier E and clutching the shaft H to the gear 0. A third speed is obtained by then releasing the carrier E and holding the ring D. If now both the carrier and ring are released and the sleeve P advanced, the cone L picks up the ring D, the teeth P<1> afterwards making a positive connexion, and the gearing turns solid yielding the fourth or highest speed. For reversed driving, the ring D is clutched to the shaft H, the carrier E being held.

Filed: 1974-06-06
Abstract: 1457152 IC engine intake passages TOYOTA JIDOSHA KOGYO KK 6 June 1974 [8 June 1973] 25229/74 Heading F1B The invention relates to an I.C. engine of the kind having a main combustion chamber 5 and an auxiliary combustion chamber 15 which communicates with the main chamber through a narrow opening 17. An inlet passage 6 is provided being controlled by an inlet valve 7 which is shown as being loaded in the closing direction by a spring 11  and openable by means of a push-rod 13 acting through a rocker arm 12. The inlet passage 6 is curved whereby a weak fuel/air mixture supplied therethrough is caused to swirl during the suction stroke. A duct 14 is disposed in the inlet passage 6 and a rich fuel/air mixture is suppled therethrough during the suction stroke, the duct 14 opening just upstream of the inlet valve 7. The rich mixture is also caused to swirl at the centre of and in the opposite direction to the swirling weak mixture such that during the compression stroke rich mixture enters the auxiliary combustion chamber 15 through the opening 17. Thus when the sparking plug 16 whose points are located in the auxiliary combustion chamber fires, the rich mixture within the auxiliary chamber is ignited and the resulting flame ignites the rich swirling mixture within the opening 17 and the swirling weak mixture in the main combustion chamber 5. The object of the invention is to avoid unburned fuel passing out with the exhaust gases. The weak mixture can be caused to swirl by a shroud on the back of the suction valve.
