    摘要: PROBLEM TO BE SOLVED: To provide a simpler and potentially less expensive method for monitoring accurate fluid metering from a gear pump.SOLUTION: A gear pump includes a housing with an inlet port 80 for receiving a viscous fluid and an outlet port 94 for discharging the viscous fluid. A driven gear 30 and an idler gear 32 are each mounted for rotation in the housing. An inlet space is in fluid communication with the inlet port, and an outlet space is in fluid communication with the outlet port. A gear 60 that is a flow indicating element is located in the housing and mounted for rotation independently of the driven gear and the idler gear. The flow indicating element is configured to be rotated by the viscous fluid to indicate when the fluid moves from the inlet port and inlet space to the outlet space and outlet port. Methods of indicating flow of viscous fluid through a gear pump are also provided.

    摘要: PROBLEM TO BE SOLVED: To suppress occurrence of wearing even when using a working fluid of low viscosity.SOLUTION: There are provided a drive rotor 7 and a driven rotor 9 which are accommodated in a casing while being engaged with each other. Both the rotors 7, 9 have an initial engaged attitude and a three-points engaged attitude. In the initial engaged attitude, teeth 7b of the drive rotor 7 are contacted with teeth 9b of the driven rotor 9 at two positions (d), (e) where they are separated from each other. The three-points engaged attitude is an attitude rotated from the initial engaged attitude and in the three-points engaged attitude, the teeth 7b of the drive rotor 7 are contacted with the teeth 9b of the driven rotor 9 further, in addition to two positions (f), (g) resulting from moving the two positions (d), (e) with the rotation, at one position (h) at an upstream side in a rotation direction rather than these two positions. Under the three-points engaged attitude, pressure in a downstream side space B between the two positions (f), (g) at the downstream side in the rotation direction is higher than pressure in an upstream side space A between two positions (g), (h) at an upstream side in the rotation direction. At the same time, a perpendicular bisector of a line segment connecting the two positions (f), (g) at the downstream side in the rotation direction is deviated from an axial center 9c of the driven rotor 9 in such a manner that a moment in the rotation direction is generated in the driven rotor 9.
