Abstract

The invention discloses a kind of internal combustion engine, this motor is divided into four chambers to circular cylinder body by two pistons that are contained in the circular cylinder body, and make two pistons constantly carry out relative movement by control system, and constantly change the volume of four chambers, finish suction, pressure, combustion, four processes of row.Though this motor has only the suitable eight cylinder reciprocating motors in firing chamber, therefore circular rotary engine is compared with reciprocating engine and is had advantages such as volume is little, in light weight, power is big.Circular rotary engine does not have bent axle, distributor etc., and the production of this motor is greatly simplified.

Description

Circular rotary engine or circular air compressor

The present invention is a new internal combustion engine, which has, compared to known reciprocating engines:

1. the structure is simple: the devices of a crankshaft, a steam distribution cam, a steam distribution valve, a distributor and the like of the reciprocating engine are omitted

2. The engine has good manufacturability, and other parts except the piston and the one-way brake are standard gears and circles.

3. The power is large: calculations indicate that the liter of power is 273 hp/liter, much larger than a reciprocating engine.

4. Compared with a reciprocating engine with the same power, the oil consumption is low.

5. Compared with a triangular rotary engine, the rotary engine has good sealing performance, and solves a fatal weakness of the triangular rotary engine.

Description of a preferred embodiment of the invention:

FIG. 1 is a sectional view taken along line I-I of FIG. 2, FIG. 2 is a sectional view taken along line II-II of FIG. 1, FIG. 3 is a sectional view taken along line III-III of FIG. 1, and FIG. 4 is a sectional view taken along line IV-IV of FIG. 1.

In the figure, (1) (2) is a rotary piston, (3) is a cylinder body, (4) is a supporting shaft, (5) is a left cylinder cover, (6) is a right cylinder cover with a gear and a brake ring, (7) is an output shaft, (8) is a left supporting disk, (9) is a duplex control gear (with a control ring), (10) is an output gear of the piston (2), (11) is a torsion spring, (12) is a right supporting disk, (13) is a gear, (14) is a gear, (15) is a clockwise one-way brake, (16) is a counterclockwise one-way brake, and (17) is a small shaft.

Referring to fig. 1, 2 and 3, the left end of the piston (1) is connected with a left cylinder cover (5) into a whole, and the right end is connected with a right cylinder cover (6) with a gear and a brake ring into a whole. The piston (2) is connected with the shaft (4) and the output gear (10) through keys and can synchronously rotate. A duplex control gear (9) with a notch and a control ring attached with a switchable clockwise one-way brake is respectively meshed with a gear on a right cylinder cover (6) and a gear (10) on a supporting shaft (4) and is connected on a shaft (7) (supported on supporting discs (8) and (12)) through a key. The right end of the output shaft (7) is connected with a gear (13) through a key, and the gear (13) is meshed with a gear (14) and outputs power. The one-way brakes (15), (16) and the torsion spring (11) are respectively sleeved on the small shafts (17), the one-way brakes (15), (16) are contacted with the brake ring on the right cylinder cover under the action of the torsion spring (11), and 8 small shafts (7) are respectively arranged on the supporting discs (8) and (12).

The combustion of the mixed gas compressed in the chamber I in figure 2 pushes the piston (1) to rotate clockwise, and the piston (2) is relatively static under the action of a counterclockwise one-way brake (16). The piston (1) discharges the waste steam of the previous cycle II chamber while rotating to do work, the third chamber sucks in the mixed steam, and the fourth chamber sucks in the mixed steam in the previous cycle and is compressed. The 180 ° rotation of the piston completes 4 processes that the reciprocating engine would have to complete after 720 ° rotation of the crankshaft. When the piston (1) rotates (see figures 2, 3 and 4), the convex part of the control ring on the duplex control gear (9) for controlling the clockwise one-way brake (15) opens the clockwise one-way brake (15), so that the one-way brake (15) is separated from the brake ring on the right cylinder cover (6), and the clockwise rotation of the piston (1) is ensured. When the gear (9) is driven by the gear on the right cylinder cover (6) to rotate anticlockwise, 4 one-way brakes on two sides of the gear (10) are in contact with the brake ring on the gear (10) and lock two rotating directions of the gear (10). The gap (toothless part) of the duplex control (9) (see fig. 4) is just engaged with the gear (10), so that the rotation of the duplex control gear (9) is temporarily independent of the gear (10). When the piston is rotated to the 1' position (chain double-dashed line position) in fig. 2, the duplex control gear (9) in fig. 4 has rotated through the notch part and is engaged with the gear (10) to drive the gear (10) to rotate, and at the same time, the convex part of the control ring of the control clockwise one-way brake (15) on the duplex control gear (9) opens the clockwise one-way brake (15) [ at this time, the right end of the gear on the right cylinder cover (6) and the intermittent clutch on the left end of the gear (10) are on ]. Under the action of the duplex control gear (9), the pistons (1) and (2) are synchronously rotated to the position shown in fig. 2, and the pistons (1) and (2) are already shifted. The duplex control gear (9) rotates to a notch (without teeth) part relative to the gear on the right cylinder cover (6). And a control ring of the control one-way clockwise brake (5) on the duplex control gear (9) also rotates to a concave position, and the one-way clockwise brake (15) falls down and is contacted with a brake ring on the right cylinder cover (6). The spark plug is ignited to ignite the mixture to push the piston (2) to rotate clockwise, and a second cycle is started.

The engine up to 274 horsepower was calculated and the following list compares several domestic engines up to 274 horsepower. The engine weight is estimated to be about 30 kg.
