形流量計。[Claims for Utility Model Registration] (1) A first bearing that pivotally supports a pair of non-circular gear rotors driven in proportion to the flow rate on a rotor shaft;
In the positive displacement flowmeter, the pair of non-circular gear rotors are rotatably supported in the metering chamber by a second bearing mounted between an end surface of the rotor and a wall surface of the metering chamber. A first groove communicating in the axial direction is provided in the bearing, and a second groove communicating with the first groove is provided.
A groove is provided in the second bearing, and a hole is formed in each of the pair of rotors from the center of the shaft toward the outer diameter, but does not communicate with each other and communicates with the first groove and the second groove. A positive displacement flowmeter characterized by: (2) The positive displacement flowmeter according to claim 1, wherein the size of the hole is at least 1/2 or less of the reference pitch of the gear of the non-circular gear rotor. (3) The positive displacement flowmeter according to claim 1, wherein the hole is located near the minimum diameter of the non-circular gear rotor. (4) The positive displacement flowmeter according to claim (1), wherein the first groove has a spiral shape.
