Abstract
332,363. Stevens, A. H., (Delco Products Corporation). June 13, 1929. Fluid-friction vibrationdampers.-In liquid shockabsorbers of the doubleacting type radial partitions divide a cylindrical casing into several interconnected compartments in each of which works a movable radial vane, the several vanes being operated from a central spindle, while flow of liquid from one side of each vane to the other is regulated in several ways as follows:- (1) spring- loaded relief valves connect the pressure sides of the movable vanes in all the compartments to the opposite sides. (2) A leak orifice preferably controlled from outside regulates the flow from one side of the vanes to the other. (3) A metering disc with a shaped edge varies the rate of leakage in accordance with the position of the operating member. Means are provided to make up for leakage of liquid by replenishment from an independent reservoir. In the construction shown in Fig. 2, 3, 4, and 5, the cylindrical reservoir is divided into three compartments by three partitions 70, 71, 72, which are held in position by spigots engaging recesses in the body of the casing and in a cover 55 which also provides a bearing for the operating spindle 50<a>. This spindle carries on its outer end an actuating lever 27 and at its inner end is formed integral with three vanes 51, 52, 53. Each movable vane thus divides the three compartments into two parts, three of which are connected by passages 84<1>, 85, 86 to a. cylindrical passage 83 running parallel to the axis of the operating spindle 50<a>, while the other sides of the partitions are similarly connected to another longitudinal passage 84. The two passages 83, 84 always communicate, whatever the position of the spindle, with corresponding openings 37, 38 in the casing, while each of these openings is further connected with vertical passages 33, 34 leading to the underside of spring loaded relief valves 36 one of which is shown in Fig. 6. The space above each of the relief valves communicates through openings 81, 82 with the spaces on each side of the fixed partition 70. When the operating spindle 50a is moved in an anti-clockwise direction, liquid flows through the passage 83 from the pressure side of each vane and upwards past the corresponding relief valve. and thence through the opening 82 to the other side of the fixed partition 70, from which it passes to the other two compartments. The other relief valve controls the resistance to movement of the vanes in a clockwise direction. The fixed partition 70 is also provided with a screw down valve 94 which regulates the flow from one side of the partition to the other. Between one end of the partitions and vanes and the corresponding face of the casing there may be interposed a thin disc 110, as shown in Fig. 7, having formed on its periphery slightly cut-away portions 112 of varying depth as shown in Fig. 5. These leak orifices 112 provide more leakage area when the movable vanes are in the central position than when they are moved in either direction therefrom. An outer cover 64 provides an oil reservoir from which the compartments may be replenished when required through openings 98 in the fixed partitions 71, 72 and one way valves 99.
