The objective of the invention is to avoid above-mentioned the deficiencies in the prior art part and a kind of rotary piston engine with better simply inlet and outlet mechanism is provided.
Purpose of the present invention can reach by following measure: its admission gear is made up of air inlet valve, air inlet valve spring, adjustment ring and valve cap, admission gear is installed on the cylinder body, the summit of five camber lines of cylinder interior is equipped with one and is packed into the mechanism of qi structure, its exhaust gear is made up of exhaust valve, exhaust valve spring, and two cover exhaust gears are installed in a pair of camber line inside of projection relatively in four toothed projections rotors respectively.
The purpose of this utility model can also reach by following measure: air inlet valve one end is a circular cone, vertex of a cone direction one end is elongated round bar, rod end has screw thread, regulating ring is oblate cylinder, the middle part has and the consistent screw of air inlet valve rod end screw thread, the exhaust valve end that is installed in the exhaust gear of rotary-piston inside is a circular cone, and awl end direction one end is elongated round bar, and the Sealing between inner chamber of cylinder block and the rotary-piston is mounted on the cylinder body.
Description of drawings is as follows:
Fig. 1 is a kind of embodiment's of the utility model a basic structure sectional view.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is the tectonic maps of air inlet valve.
Fig. 4 is the tectonic maps of exhaust valve.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1, Fig. 2 is a kind of embodiment's of the utility model a basic block diagram, rotary-piston (8) is fixed on the bent axle middle part, one side of rotary-piston (8) is planetary pinion (12) fixedly, rotary-piston (8) is connected with sliding bearing with bent axle (2), the inboard of front end housing (4) embeds fixedly ring gear (11), its planetary pinion (12) is 4:5 with the speed ratio of fixture gear ring (11), the spindle hole internal fixation sliding bearing of front end housing (4) and back cylinder cover (9), rotary-piston (8) is inserted in the inner chamber of cylinder body (6), to be inserted in before and after front end housing (4) and the back cylinder cover (9) again, fastening in addition with connecting bolt, the interior camber of cylinder body (6) is the inner rotary line, the camber line number is five in the cylinder body, the outer arc line type of rotary-piston (8) is the inner rotary line, camber line limit number is four, the one air inlet cavity volume that protrudes is all arranged at the top of five camber lines of cylinder body (6), in order to air inlet valve (15) to be installed, air inlet valve (15) is inserted air inlet cavity volume endoporus, be inserted in air inlet valve spring (13), again regulating ring (23) is screwed in air inlet valve (15) rod end, cover the admission gear that can form five Normally closed types behind the valve cap (14), in the air inlet cavity volume air flue is arranged, oil spout joint (16) is gone up oil nozzle is installed, communicate with air flue, the inside of rotary-piston (8) has exhaust port in relative a pair of toothed projections place correspondence, interior dress exhaust valve (20) and exhaust valve spring (21), form two cover exhaust gears, each air inlet cavity volume of cylinder body (6) be attached with spark plug (19), the front end of bent axle (2) is fastened on bent axle on back with nut (17) fastening and axially locating after with fan blade (1) with key with connecting sleeve (3), the dust-proof cover (18) of packing into, flywheel (10) is connected the rear end of bent axle (2) with key, and the output that is used as power.
Air inlet valve (15) one ends are circular cone as shown in Figure 3, and vertex of a cone direction one end is elongated round bar, and rod end has screw thread, use conical surface as sealing surface.
Exhaust valve (20) one ends are circular cone as shown in Figure 4, and awl end direction one end is elongated round bar, makes sealing surface with conical surface.
Motion conditions of the present utility model is such, because the inner chamber camber line of cylinder body (6) and the camber line of rotor surface are the inner rotary lines, planetary pinion (12) fixing on rotary-piston (8) sidewall is mutually meshing with the inboard fixing ring gear (11) of front end housing (4), and gear ratio is when being 4:5, its wound becomes the inner rotary line identical with rotor surface with cylinder body (6) inner chamber camber line, like this, when bent axle (2) rotates, the toothed projections on rotary-piston (8) surface that the inner rotary line of five sections arcs of cylinder body (6) inner chamber is contained will constantly be slided along cylinder body (6) surface of internal cavity, when the intersection of (6) five arcs of every cylinder body is installed Sealing (7), form the active chamber of five separations, and the volume of each active chamber changes constantly.When each active chamber enters the mixed combustible gas body and then finishes four strokes of air inlet, compression, expansion, exhaust in the similar reciprocating-piston engine when providing electrical spark in each active chamber successively by spark plug (19) on time, and promote constantly rotation of rotary-piston (8), by flywheel (10) output power on the bent axle (2).Because four strokes of each active chamber are finished successively, the utility model is installed two exhaust valves (20) and in rotary-piston (8) exhaust passage is arranged in the inside that (8) one relative two of rotary-pistons protrude toothed surface, exhaust valve (20) not only can satisfy the needs of five active chamber exhausts successively like this, and can make exhaust valve (20) avoid calming the anger in each active chamber and expanding two high pressure stroke, to improve the efficient of motor.
The utility model has following advantage compared to existing technology:
