JPS6138184A - Pump constructed with combination of rotary cubes - Google Patents

Abstract

PURPOSE:To exhibit function of pump with simple structure by combining cubes having oval cross-section while continuously contacting the sidefaces of adjoining cubes then rotating them and utilizing the variation of space to be produced in the center. CONSTITUTION:Cubes 2 having oval cross-section are combined such that the sidefaces of adjoining cubes 2 will contact each other then they are rotated simultaneously in same direction with same speed. The space in central section will be smallest when the sidefaces at one end of thin section of cubes 2 are collected in central section while largest when they are opened outward entirely. Expansion and contraction of said space 3 are repeated as the cubes 3 rotate. When applying flatboards 4 to the upper and lower sections of the cubes 2 to enclose the central space section 3 and fixing suction and discharge valves to the upper and lower sections, the function of rotary pump can be exhibited through simple structure.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a pump having a structure in which cubes having an oblong cross section are combined and rotated.

Conventional pumps use reciprocating motion of power to increase and decrease pressure, or some apply circular force, but reciprocating motion like that of a piston causes loss of power energy and severe vibration during repetition, and also , those that apply centripetal force have limitations in terms of pumping pressure, etc. Other rotating systems include a rotary set, but their internal structure is complicated.

In the present invention, oval cubes are assembled so that the side surfaces of the cubes are in contact with each other as shown in FIG. 1, and the cubes are rotated in the same direction and at the same speed at the same time as shown in FIG. 2.

(a) The shape of the combined cubes must be such that they are in constant contact with the sides of the cubes on both sides.

) When the sides of one end of the thin part of a cube converge in the center, the space in the center becomes the narrowest.

(c) When all of the thin parts of a cube are opened outward, the space in the center becomes the widest.

By rotating the cube, the space in the center becomes wider, narrower, and wider again, and this process is repeated.

A flat plate is placed at the top and bottom of this cube to seal the central space as shown in Figure 3, and water intake (intake) valves and drainage (exhaust) valves are attached to the top and bottom.

The present invention is a rotary type pump having a simpler structure than a rotary set.

The structural principle of this invention is that when pressure is applied to the central space,
Since the four cubes rotate, they can be used for internal combustion engines, hydraulic power,
Also used in steam engines, etc.
