Title: Improvements in shock absorbers
IPC: F16F9/14
Filed: 1929-05-27
Abstract: 332,990. Tippen, F. J. May 27, 1929. Fluid - friction -vibration - dampers. - Vehicle liquid shock-absorbers of the rotary-oscillating- vane type are provided with a plate or member which is automatically moved into a position to allow relatively free flow of the liquid during movement of the spring away from the normal position either upwards or downwards and is automatically moved into a position in which it restricts the flow of liquid during the return movement of the spring to the normal position. A casing 1 bolted to the frame of the vehicle is divided by fixed partitions 4, 5 into two compartments in which work vanes 7, 8 carried by a shaft 6, to the outer end of which is keyed an operating arm 37 connected to the axle. Opposite compartments are connected by passages 14 in the vanes 7, 8 to ensure equality of pressure. The flow from one compartment to the other is free or restricted according to the position of the plate 10 which is free to move within limits about the spindle 6. One side of the plate is formed with an extension 15 which fits closely a recess in the abutment 4 in certain positions, while the diametrically opposite side of the plate 10 is formed with a number of teeth or notches 16 which fit close to a curved part of the abutment 5. The plate is also provided with shoulders 12, 13 which limit its movement relatively to the vanes 7, 8. When the vanes move in either direction away from the normal position in which they are shown, the pressure of the liquid forces the plate 10 rapidly in the same direction until checked by the shoulder 12, or 13. The liquid then flows freely through the passage 9 and allows free movement of the vehicle springs away from the normal. On the return movement the liquid pressure forces the plate 10 backwards into a position in which the projection 15 restricts the flow of liquid through the passage 9 until the vanes are close to the normal position thus retarding the return of the springs. A separate passage 26 independently controlled by a hand lever 27 may be provided. In one modification only one abutment and one movable vane are provided, while in a further modification in which the plate 10 is arranged against a shoulder on a reduced part of the shaft 6, grooves may be provided in the face of the plate 10 or in the cover in order that the liquid may have access to the teeth which may be arranged on the inside of the plate.
