Abstract

See full text

The invention relates to a fluid meter (27) comprising a housing (28) defining at least one crankcase (29) and two cylinders (25, 26), a crankshaft (11) disposed in the crankcase (29), two pistons (3, 4) respectively mounted in the cylinders (25, 26) for reciprocal movement, a first connecting rod (12) connected to one of the pistons (3) and to the crankshaft (11) for rotating the crankshaft (11) in response to the movement of the one piston (3), and a second connecting rod (13) connected to the other piston (4) and to the crankshaft (11) for rotating the crankshaft (11) in response to the movement of the other piston (4), wherein the first and second connecting rods (12, 13) have yoke slots (16, 17) for receiving a crank pin (19) radially offset from the crankshaft (11). The invention is characterized in that the first connecting rod (12) has a guiding rod (20) extending in a longitudinal direction of the cylinders, the guiding rod (20) being adapted to engage a corresponding cavity (22) in the second connecting rod (13) to support and guide the connecting rods (12, 13) in relation to each other during movement. The invention further relates to a multiple fluid meter assembly (61) comprising at least two fluid meters (27) as defined above, and to a fuel dispensing unit comprising a fluid meter (27) or a multiple fluid meter (61) as defined above.
