Abstract: 1525674 Expanding-pulley gear VAN DOORNES TRANSMISSIE BV 31 Jan 1977 [9 Feb 1976] 03784/77 Heading F2D In expanding-pulley gearing having driving and driven pulleys 1, 2 adjustable by hydraulic pressure in piston-and-cylinder units, the tension in the transmission belt 9 is controlled by regulating the pressure supplied to the cylinder of pulley 2 with a control valve 18 and a further control valve 42 regulates the supply to and discharge from the cylinder of the other pulley 1 to adjust the transmission ratio. The pressure adjusted by the valve 18, in a supply line 16, is controlled by the speed of pulley 1 as measured by a Pitot tube 33 in a rotating fluid-filled space 32, the pressure, proportional to speed, being applied to one end of the spool 22 of valve 18. A spring 37, whose bias is adjusted in dependance on transmission ratio by a link 40 to the movable flange of pulley 2, opposes the speed responsive pressure so that the belt tension is dependent both on input speed and transmission ratio. The valve 42 has a spool 43, also acted upon by the speed responsive pressure from the Pitot 33 in opposition to a spring 45. The valve spool is in a neutral position, pressure neither being supplied to nor discharge from the cylinder space 11 of pulley 1, when the speed responsive pressure balances the spring force, an increase or decrease in input speed reducing or increasing transmission ratio respectively. The bias of spring 45 is adjusted by the inlet manifold depression of a driving I.C. engine acting on one side of a diaphragm 50 to move a piston 49. A valve 58 is electrically operated during braking to reduce the effect of the increased vacuum in the manifold when the vehicle is braked. The bias of spring 45 may also be controlled by the accelerator pedal through a mechanical link. A brake having a cylinder 74 and a shoe 79 may be operated when a clutch, between the drive motor and the driving pulley 1, is disengaged. The overflow from valve 18 is used for lubrication. The area on which the fluid pressure acts is greater for pulley 1 than for pulley 2.

Abstract: A combustion process and apparatus for a spark ignited air compressing internal combustion engine with direct injection of the major portion of the fuel onto the wall of the combustion chamber provided in the piston in the form of a body of revolution, according to which a rotary motion is imparted upon the inflowing air in such a way that the fuel is gradually released from the combustion chamber wall and mixed with the air in the form of vapors. The injection nozzle is positioned in the cylinder head near the combustion chamber throat while the ignition device extends into the combustion chamber at the top dead center position of the piston. The fuel is injected onto the combustion chamber wall by means of a jet from which individual small fuel particles are detached which are immediately mixed with the air on being emitted from the injection nozzle opening. The small amount of combustible mixture formed by the fuel particles detached from the fuel jet and not yet conveyed by the centrifugal forces onto the wall is toward the end of the injection phase ignited close to the injection nozzle opening by the ignition device. The thus initiated combustion propagates in the direction of the revolving air across to the fuel film existing on the wall of the combustion chamber in the piston. Subsequently the main combustion takes place in conformity with the progress of the mixture of the fuel vapors generated in the wall region with the air circulating in the combustion chamber.
