Japanese Patent JP2001510521
Kind Code:
A
Abstract:
A fluid pump includes a fluid-tight housing containing two spaced, externally-toothed pulley wheels, an internally-toothed drive belt that wraps around and engages the teeth of the two pulley wheels and moves as they rotate, and a guide block in the space between the two pulley wheels. The housing includes a fluid outlet port adjacent where the drive belt engages a first of the two pulley wheels to discharge fluid pressed out from between the teeth of the drive belt, and a fluid inlet port adjacent where the drive belt disengages from the first pulley wheel. The guide block defines a first face that extends with the drive belt to a nip where the drive belt engages the first pulley wheel and a second face that includes a first portion which extends from the first face in an arc around the periphery of the first pulley wheel and a second portion which extends away from the periphery.
