Abstract
325,355. Jonsson, G. E. Jan. 17, 1929. Cow-milkers. - In pulsators for milking- machines wherein two valves 11, each controlling a high-pressure inlet 9 to, and a lowpressure outlet from, a valve chamber 8, are actuated by piston or diaphragm devices 4, which are set in motion by difference of fluid pressure in the supply lines 18 and co-operate with a spring device causing a sudden reversal of the valves, the valves are actuated by a double-armed lever 21 connected to the piston or diaphragm .device by a roller co-operating with the wedgeshaped end of a spring-actuated member. As shown, the two-armed valve lever 21 is integral with the guide 22 of a plunger co-operating by its wedge-faced end 23 with a roller 26 on a lever 19 connected to pistons 4 which are alternately acted upon by atmosphere and by vacuum through adjustably controlled passages 7. In modifications, the roller is carried by the valve-lifting lever, the pistons are replaced by. diaphragms, or a single diaphragm or a single piston disposed towards the bottom of the chamber 15 is employed. The single diaphragm or piston may carry the wedge-shaped faces on a spring arm. To prevent racing of the apparatus should the pressure difference be suddenly increased above the normal, the diaphragm &c. may be combined with a dashpot.
