Abstract

Compared with the piston mechanism used at present, the rotary triangular piston mechanism has the advantages of small friction, less movable parts, direct energy transmission, simple structure, small volume, low energy consumption, high efficiency, large output power, good continuity and the like. The method is suitable for various compression devices, such as internal combustion engines, compressors and the like.

Description

Rotary triangle piston compressing technique

Rotary triangle piston mechanism belongs to compression technique area, triangle piston mechanism comparatively advanced before this invention is the sealed type triangle piston mechanism (with reference to documents US4968234) that the American invents, this mechanism comprises housing, is configured in three triangle pistons in the housing and the seal element between the piston.This triangle piston mechanism is owing to take the extruding of sliding, and frictional force is bigger between triangle piston and the seal element, and particularly its sealing is difficult to guarantee when triangle piston runs up, and compression effectiveness is not obvious.

Purpose of the present invention is exactly to overcome the shortcoming that existing triangle piston mechanism exists, and a kind of good multi-piston type rotary triangle piston mechanism of sealing of piston space contact is provided.

Rotary triangle piston of the present invention mechanism comprises housing, and is configured in a plurality of triangle pistons that are engaged with each other in the housing.Its principle utilize four or more each other the triangle piston of tight engagement make relative rotary motion and the spatial variations of producing realizes compression.In order to guarantee that the relative rotation between each piston is that rotating speed will equate, and the contact between each piston can not gappedly be a sealing.The one, the circle-arc tooth limit is made on the limit of triangle piston, thereby guaranteed the rotating speed unanimity of each triangle piston; The 2nd, triangle piston is arranged in 3 * 3 modes, thereby the mid point that makes four triangles in diagonal angle draw together plug can fix, play squeezing action, guaranteed that no gap produces between each triangle piston.

It is simple in structure in rotary triangle piston mechanism, and volume is little, and movable part is few, frictional force little (change activity friction is rolling friction), thereby in advantages such as to be applied to have energy consumption on the compression device low, and efficient height, momentum directly pass and change, and output power is big, and continuity is good.

Fig. 7 is for being applied to the internal combustion (IC) Engine Design schematic representation.

Below just the present invention be applied to the internal combustion (IC) Engine Design design and be described as follows:

As shown in Figures 2 and 3, whole rotary triangle piston mechanism is by housing 7, top cover 5, valve gap 6 and be configured in 9 triangle pistons 1 in the housing 7, and main shaft 2, countershaft 3, bearing 4 are formed.And on housing 7, top cover 5, valve gap 6, be drilled with housing inlet hole 10, housing exhaust port 11, top cover inlet hole 8, top cover exhaust port 13 respectively, valve gap inlet hole 9, valve gap exhaust port 12.Triangle piston 1 in the described mechanism should be engaged with each other and make relative rotary motion, and the limit of triangle piston 1 makes the circle-arc tooth limit, and to guarantee that rotating speed is identical, 9 triangle pistons 1 are arranged according to 3 * 3 ranks, and the mid point of four triangle pistons 1 in diagonal angle can be fixed.For simplicity, the rotation situation of only getting four pistons in the rotary triangle piston mechanism is that " single cylinder " illustrates, as shown in Figure 5, the inlet hole 9 of beginning valve gap is opened, in the mixed gas inlet chamber of gasoline and air, rotation (both rotating speeds were not all 2/3: 1) along with triangle piston 1 and valve gap 7, and wherein 2 triangle pistons 1 and valve gap 7 are pressed the A direction and are rotated, and 2 triangle pistons 1 press the rotation of B direction in addition, when going to the air-breathing end of Fig. 5 (b), the inlet hole 9 of valve gap is closed, the compression beginning.When going to Fig. 5 (c), the volume minimum, compression finishes, and spark plug 14 igniting are as Fig. 6, and acting begins.Gas is lighted, and the gas of expansion produces moment to 4 piston tip, and direction is opposite each other, because the action of inertia piston will continue to rotate according to original direction.When going to Fig. 5 (d), acting finishes, and valve gap exhaust port 12 is opened, exhaust begins, and up to the state that recovers Fig. 5 (a), next circulation will begin again, also can with intermediate piston 1, reach inlet hole 9 by Fig. 7 design and installation, exhaust port 12, spark plug 14 fixed-site, triangle piston 1 around allowing, not only rotation but also revolve round the sun, but simplification device is saved material.
