Abstract

PURPOSE: To form highly efficient gear pump which can obtain high pressure output fluid by so constituting the convex which tapers off at the top of the gear that it slides on the inner wall of the outer casing.
CONSTITUTION: 1 is outer casing with the fluid inlet port 2 and the outlet port 3. 4 and 5 are the circular synthetic resin gears which can be engaged to each other and are contained in the outer casing 1.6 is the space between the gaps 7... of the gears 4, 5, and the convex 9 is designed to contact the inner wall 8. Since the device is so constituted that the tapering off-convexes 9 at the top of the gears 4, 5 slide on the inner wall 8 of the outer casing 1, the fluid in the space 6 is effectively sent to the outlet port 3 without flowing out to the convex 9, and at the same time, high pressure output fluid can be obtained.
