Abstract
629,896. Liquid meters. STOPPANI AKT.- GES. Oct. 3, 1946, Nos. 29555 and 29556. Convention dates, Oct. 5, 1945 and Sept. 28, 1946. [Class 69 (ii)] In a liquid-flow meter comprising two cylinders lying side by side with their interiors connected with each other at one end and two rotable and axially-movable pistons one in each of the cylinders, there is provided a measuring-chamber defined by the interconnected ends of the cylinders and limited by the piston ends facing the mutual connection of the cylinder interiors as well as two separate measuring-chambers in the cylinders at the other side of the pistons, control ports in the walls of the cylinders and control openings in the walls of the pistons, and means for causing oscillation of the pistons to change the mutual positions of the control ports and openings to control the inlet and outlet to and from the three measuring-chambers. Within a cylinder block 2, Fig. 1, are two parallel bores 3 and 4 each having separate measuring- chambers I, II, Fig. 5, respectively, at one end and both communicating at the other end with the third measuring-chamber III. Liquid flowing through the chambers causes reciprocating motion to be imparted to pistons Ka and Kb ; the pistons are arranged to have a mutualoperating phase-displacement of 120 degrees. Each piston Ka, Kb has a ball-and-socket joint halfway down its length which through a pivot 11 is connected with a gear-wheel 12 so that the reciprocation of each piston causes it to also experience an oscillating rotary motion and to thereby enable each piston to control ports in the lower half of the diameter of the bore and its own periphery. Both gearwheels 12 are connected with a totalizer or counter (not shown). Piston Ka embodies three ports EK1, AK1, Fig. 1, and K3, Fig. 6, whilst piston Kb has an identical arrangement of ports. Cylinder bore 3 is provided with two slots EZ1 and AZ1 which in conjunction with the piston ports EK1 and AK1 comprise the inlet and outlet to and from chamber I. Two further slots EZ3, AZ3, Fig. 5, in the cylinder bore 3, together with port K3 in the piston Ka constitute the inlet to and outlet from chamber III. Four similar slots in cylinder bore 4 and the three ports in piston Kb provide access to chambers II and III. In a modification the slots and ports in the cylinders and pistons respectively are located in both the upper and lower parts of the diameter, there being six ports in each piston and eight slots in each cylinder bore. The pivot of each piston is connected to a disc on the shaft of a bevel wheel, both of which latter are in mesh. The shaft of one bevel wheel is connected to. operate the counter. The number of ports in each piston may be reduced to two. The liquid entering the meter takes two paths, one part supplying the upper ports and the other the lower ports both streams re-uniting prior to discharge.
