Abstract

602,294. Pulsators of milking-machines. AKTIEBOLAGET SEPARATOR, and RAMQVIST, T. T. Nov. 19, 1945, No. 31013. [Class 84] The pulsation-frequency control of a cow-milker comprises two compartments 1, 2 containing air or other fluid and connected by a throttled passage 3 in a fixed dividing wall 11, a flexible diaphragm 4 of one compartment 1 being linked at 32 with valve-stems 28 and 30, whereby suction from a line 20 reaches a compartment 6 &c. to move the diaphragm so that pulsations are generated, the valves &c. linking the teat-cup lines 25, 27 with the pulsator, Slow air leakage is provided as by use of porous diaphragms, by piercing the diaphragms or by passages 8, 9, or by a passage 11 leaking to the atmosphere, for equalizing the pressure in the enclosure 1, 2, or alternatively this could be effected by a valve to open only when the pulsator is at rest.
