Title: Liquid enclosing type gas pump
Inventor: ITO EIICHI
IPC: F04C19/00
Filed: 1985-03-25
Abstract: PURPOSE:To raise the processing precision for a casing and the discharging efficiency, by forming a groove on a side board which confronts the side surface of an impeller, and making a liquid ring to be eccentric through making a part of the liquid enter into said groove, so as to make the inner circumference of the casing to be a true circle and to be concentric with the impeller. CONSTITUTION:When a proper quantity of liquid is enclosed in a casing 3 and an impeller 1 is rotated, the liquid is rotated with the impeller 1 along the inner circumferential wall 4A of an outer cylinder 4 by centrifugal force, and a liquid ring 14 whose outer circumference is contacted with the inner circumferential surface 4A of the outer cylinder 4, is formed. When this liquid ring 14 confronts a groove 10 which is formed on a side board 5A, 5B, as it extends along the circumferential direction, and into which one end of a connection hole 13 opens, a part of the liquid ring 14 enters into this groove 10, and the inner circumferential surface of the liquid ring 14 becomes eccentric. By this matter, the inner circumference of the casing 3 (the outer cylinder 4) which confronts the outer circumference 1A of the impeller 1, can be made to be a true circle, and the center of this circle and the center 0 of the impeller 1 become the same. Consequently, the machine processing can be performed easily and precisely. Moreover, the discharge efficiency can be equalized, as the gap between the inner circumferential surface 4A of the outer cylinder 4 and the outer circumferential surface 1A of the impeller 1 becomes smaller and even.

The switching state is maintained in the state of turning off the power source and the electric power is saved. In addition, the decoloration or color development is generated by the oxidation reduction in the opposite direction of this ECD, by which the switching state is inverted.
