Abstract

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) with a circumferential periphery (62) for receiving a crank pin (19) radially offset from the crankshaft (11). The fluid meter (27) is characterized in that the circumferential periphery (62) of each one of said yoke slots (16, 17) has at least one resilient portion (61) for allowing a play? between said crank pin (19) and said circumferential periphery (62) of said yoke slot (16, 17) at said at least one resilient portion (61). 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.
