Abstract

1297284 Milking machine pulsators. WARTSILA Ab Oy 12 Feb 1970 [13 Feb 1969] 6744/70 Heading AIM [Also in Divisions G3 and F2] In a pulsator wherein a hollow reciprocating piston rod 2 interconnects two identical pistons 1, each of which pistons carries a diaphragm 3 defining a closed, fluid containing space 4, damping of the reciprocatory motion of the rod 2 is effected by inserting a grooved plug 6 into one end of the piston rod bore 5, which bore is of smooth cylindrical form, such that the plug groove acts in conjunction with the bore 5 to provide a throttling passage 8. The plug is formed with a blind axial bore 10 which facilitates the insertion and subsequent retention of the plug 6 within the piston rod 2, and the bore 5 is enlarged as at 9 such that the length of the throttling passage may be varied by altering the degree of penetration of the plug 6 within the bore 5. In a modification, not shown, the plug is formed with a smooth outer surface whilst the bore is grooved.
