The gears are rotatably supported at support holes of a pair of side plates via support shafts. As viewed in an axial direction of the support shafts during rotation of the gears, addendum circles of the gears displaced under a differential pressure between a low-pressure chamber and a high-pressure chamber form first contact points with respect to an inner peripheral surface that defines a housing hole. As viewed in the axial direction of the support shafts during rotation of the gears, the first contact points are covered with the side plates displaced under the differential pressure. | ||||||

| 17 | Device having a sealed control opening and an orbiting valve | US282675 | 1988-12-12 | US4877383A | 1989-10-31 | Hollis N. White, Jr. |
| A gerotor device is disclosed wherein the pressurized fluid is segregated to the area of the device near the orbiting valve by the sealing of the wobblestick drive connection to the valve. In the preferred embodiment shown this sealing is accomplished by restricting the effective size of the drive opening through the valving plate of the manifold plate to an area less than that capable of being sealed by the inside drive surface of the valve. | ||||||
| 18 | Gear pump with leakage fluid intermittently communicated to expanding fluid cells | US79265 | 1987-07-29 | US4770617A | 1988-09-13 | Siegfried Hertell |
| A gear pump is disclosed which is adapted to convey a polymeric melt without significant leakage, and which comprises a pair of intermeshing gears. One of the gears is driven by a drive shaft which extends through a journal bore in the pump housing, and a by-pass duct extends between the journal bore and an area in the internal chamber of the pump which is adjacent but spaced from the intermeshing teeth and where the fluid cells defined by the intermeshing teeth are expanding. Also, at least one root of one of the gears includes a channel which leads to the area of the by-pass duct, and so that an intermittent suction resulting from the expanding fluid cells acts to withdraw any melt from the journal bore of the drive shaft and through the by-pass duct, to thereby prevent leakage of the melt outwardly through the journal bore. | ||||||
