PURPOSE:To simplify the structure and permit the liquid having a high viscosity to be transported under pressure by utilizing such phenomenon that a rotor is revolved eccentrically in a casing by the revolution of an eccentric revolution shaft and the volume between the both sides of the rotor and the inner wall chamber of the casing CONSTITUTION:An eccentric revolution shaft 3 is arranged at an eccentric position in a semicircular casing 1 which consists of the upper part in elliptic form and the lower part in circular form. When a rotor 2 fitted on the shaft 3 of revolution is revolved, the both ends of the rotor 2 closely contact with the inner wall of the casing 1 in deformed circular form and revolve. Wiht the utilization of the variation of volume of the space between the inner wall of the casing 1 and the both sides of the rotor 2, liquid is inhaled from the opening 4 and discharged from an opening 5. In this case, the necessity of pushing the rotor 2 by a spring is obviated, and a small pump having a simple structure and in high speed revolution is obtained , and the pump can be applied to the transportation under pressure of the mixes of mortar and a liquid having a high viscosity. |
