Title: A device for supplying a measured quantity of liquid
IPC: B67D7/64
Filed: 1946-07-01
Abstract: 610,596. Delivering measured quantities of liquids. BULLOCK, S. E., KENDRICK, W. E., and FAULKNER, T. H. July 1, 1946, No. 19597. [Class 106(v)] A device for delivering a measured quantity of liquid from a supply under pressure comprises a nozzle 12 and an annular measuring chamber 24 containa free piston 43. The inner wall of the chamber is defined by a valve sleeve 14 formed with ports 36 at its ends and containing a tubular valve structure 17 rotatable by a handle 42 and comprising a tube 21 formed with two pins 18 engaging a central slot in an apertured throttling disc 19 controlling two series of ducts 61, 62 leading to the delivery outlet 59. The seal between the sleeve and tube comprises two semi-cylindrical members 26 fixed to the tube on opposite sides thereof and formed with ports 32 aligned with ports '34 in the tube, and two complementary loose members 27 formed with ports 35 and urged outwardly by springs 31. The supply is connected to the tube at 20 and, with the handle in the position shown, liquid flows through the left-hand ports 34, 36 to move the piston 43 to the right and fill the chamber 24. The handle is then rotated 180 degrees, and liquid now flows through the right-hand ports 34, 36 to move the piston to the left, thus displacing the measured quantity through the left-hand ports 35, 36, which are now aligned, into the chamber 25. Pressure built up in this chamber moves a spring-loaded piston 64 coupled by a spring toggle 67, 68 to a valve member 63 normally closing the outlet 59, and when the toggle is moved beyond the dead centre position it operates to withdraw the valve member, thus opening the outlet and allowing flow through the ducts 61, 62. When the measured quantity has been delivered, the pressure drops suddenly and the piston 64 is then moved to the left by its spring to return the toggle to the position shown in which it holds the member 63 against its seat. The rate of flow may be varied by turning the handle 42 to rotate the throttling disc 19. At the ends of its strokes, the piston 43 engages rods operating a ratchet wheel 44 of a counting mechanism, the wheel being advanced one tooth for each stroke. Specifications 610,601, [Group XXIX], and 610,602 are referred to.
