Abstract: 544,313. Fluid-pressure servomotor control systems. DUGAS, J. J. Oct. 31, 1940, No. 15905. Convention date, Nov. 24, 1939. [Class 135] A vacuum servomotor system for moving the clutch of a marine transmission into the neutral, forward or reverse positions includes a manually actuated control device, comprising a ported annulus 21 arranged between a ported plug 17 and a fixed ported seating 13 and having a lostmotion connection with the plug. The seating is connected by pipes 8, 9 to the two ends of a power cylinder 2 and by a pipe 10 to the midpoint of the cylinder and is provided with two ports 15, 16 leading to atmosphere. In the position shown in Fig. 3 which corresponds to the neutral position of the clutch an axially arranged suction pipe is connected by a right-angled passage 20 in the plug and an elongated port 22 with the pipe 10 obturated by the piston 3 while the pipe 8 is connected to atmosphere by ports 25 in the annulus and a pocket 27 in the plug. To move the clutch into the forward position the hand lever 12 is moved towards the bow of the vessel. This first takes up the lostmotion between the key 29 and the end of the port 22 and then both plug and annulus move together to connect the pipe 8 to suction by way of port 22 and passage 20 and the pipe 9 to atmosphere by way of pocket 24 in the annulus and port 16. To move the clutch to the reverse position the valve is moved to the position in which the pipe 9 is connected to suction by way of port 22 and passage 20 and the pipe 8 is connected to atmosphere by way of pocket 23 and port 15. Fig. 3 shows the position after the return to neutral after a forward clutching, when returning to neutral after reverse clutching the key 29 is at the other end of the port 22, but the handle is in the central position. Movement of the annulus is limited by a pin working in a slot in the casing and a detent 32 imparts frictional pressure to the annulus and gives the desired amount of stiffness to the operation of the valve. The movement of the power piston is communicated to the clutch lever 1 by two links 5, 6 connected by a catch 40 formed with a tail adapted to contact with a stop and release the catch as the clutch lever reaches its forward position. Cams 33, 34 on the link 5 operate through a link 35 to throttle the engine during the movements of the clutch from one position to the other.

Title: Improvements in and relating to suspension systems of vehicles
IPC: B60G21/06
Filed: 1957-05-22
Abstract: 857,670. Road vehicle spring suspensions. REGIE NATIONALE DES USINES RENAULT. May 22, 1957 [June 5, 1956], No. 16258/57. Class 108(2) In a vehicle suspension system the front and rear wheels on the same side of a vehicle are hydraulically interconnected, through pistons 3, Fig. 1, cylinders 1, or a central cylinder 7. The cylinder 7, Fig. 2, houses a compression spring 5 between pistons 6 which transmit pressure from the road wheels, and a rebounddamping cylinder and piston 16, 15 which allows relatively free compression and damped expansion of the spring 5. Return springs 8 assist in maintaining the system in balanced condition. Spring compression may be retarded if necessary by an orifice 14 in a non-return valve 13. In the embodiment shown in Fig. 3, partial choking of the pipe lines to the front axles is provided during braking by brake actuated pistons 18, Figs. 2, 3, thus stiffening the front suspension and, preventing longitudinal tilting of the vehicle body. A branch pipe 20 and a gaged valve 21 limit the stiffness in case the brakes are applied whilst traversing rough ground. The lateral assemblies may be connected by pipe line 22, Fig. 4. A valve 23, controlled either mechanically or by an inertial weight, closes the pipe 22 when the vehicle body is laterally inclined beyond a predetermined limit. The two lateral assemblies may be connected at both front and rear, by pipes 24, Fig. 5, each having a rolling movement corrector. When a valve 34 is actuated, in the same way as the valve 23, fluid is supplied under pressure through a pipe 37 to either end compartment 29 or 29<SP>1</SP>. This pressure acting on either piston 28 or 28<SP>1</SP> moves a three piston assembly 28, 26, 28<SP>1</SP>, connected by a rod 30, either right or left, to close a passage 36 between suspension cylinders 7. During this movement a piston 26 draws fluid from one of suspension cylinders 7 and forces the same quantity into the opposite cylinder 7. The action of the valve 34 is so arranged that this transfer tends to correct the lateral canting of the vehicle. Springs 35, 35<SP>1</SP> restore the piston 26 to its rest position when lateral canting has ceased. The suspension spring may be divided into two halves 38, 38<SP>1</SP>, Fig. 6, which bear against a flange 39 carried by a bellows 40. Application of the brakes causes shoes 41 to press against the bellows 40 to lock them, thus suppressing interaction between front and rear axles. Body height may be adjusted, the necessary fluid control valve being opened and closed manually or electromagnetically. A pair of pointers may be provided on the instrument panel which register with each other and close the levelling valve when the vehicle body is horizontal or parallel with the ground. The levelling valve is locked closed when the vehicle is in motion.
