Abstract
The utility model discloses a double-piston double-crankshaft type engine, which comprises a cylinder, pistons, crankshafts, connecting rod shafts, a connecting rod, an air inlet door, an air outlet door and a spark plug or nozzle tip, wherein a left piston and a right piston are arranged in the cylinder; the left piston is connected with a left connecting rod shaft on a left crankshaft through the connecting rod; the right piston is connected with a right connecting rod shaft on a right crankshaft through the connecting rod; the air inlet door and the air outlet door are arranged in the middle of the cylinder; the spark plug or nozzle tip is arranged on one side of the air inlet door; a first left connecting rod shaft is connected with a first right connecting rod shaft through a first long connecting rod; a second left connecting rod shaft is connected with a second right connecting rod shaft through a second long connecting rod; the first long connecting rod and the second long connecting rod have the equal length; and valve stem conversion devices are respectively arranged at positions of the air inlet door and the air outlet door. The double-piston double-crankshaft type engine is simple in structure and convenient to manufacture, so that high-pressure gas in a combustion chamber is changed from the original unidirectional working mode to bidirectional working mode, and the application are wide.
Description
Technical field
The utility model relates to a kind of motor, particularly double-piston hyperbolic shaft type motor.
Background technique
All has only a piston in present known DENG or each cylinder of petrol engine; Gas pressure intensity was only to a direction acting when compressed fuel mixture burnt when cylinder; Do not do work in the other direction, still do not have in the market can two-way work doing motor.
Summary of the invention
The purpose of the utility model is to provide a kind of double-piston hyperbolic shaft type motor that can two-way work doing.
The technological scheme of the utility model is following:
Double-piston hyperbolic shaft type motor; Comprise cylinder, piston, bent axle, pitman shaft, connecting rod, intake valve, exhaust valve, spark plug or nozzle tip; Be provided with left piston and right piston in the cylinder, left piston links to each other with left pitman shaft on the left bent axle through connecting rod, and right piston passes through connecting rod and links to each other with right connecting rod axle on the right bent axle; The cylinder neutral position is provided with intake valve and exhaust valve; Spark plug or nozzle tip are installed in intake valve one side, and the first from left pitman shaft links to each other with a right pitman shaft through first long connecting rod, and the second from left pitman shaft links to each other with right two pitman shafts through second long connecting rod; The equal in length of first long connecting rod and second long connecting rod, the position of intake valve and exhaust valve are respectively installed a valve stem conversion equipment.
Said the first from left pitman shaft and the second from left pitman shaft differ 90 degree with respect to angle, left bent axle axle center, and a right pitman shaft and right two pitman shafts differ 90 degree with respect to angle, right bent axle axle center.
The advantage of the utility model is:
1, simple in structure, easy to make, can be widely used; 2, the utility model make in the firing chamber pressurized gas from before unidirectional acting be transformed into two-way work doing, purposes is more extensive.
Description of drawings Fig. 1 is the utility model overall structure schematic representation;
Fig. 2 is the utility model valve stem conversion device structure schematic representation.
[0008]Embodiment is described further the utility model below in conjunction with accompanying drawing.
Can see the structure of the utility model by Fig. 1; Double-piston hyperbolic shaft type motor comprises cylinder 4, piston, bent axle, pitman shaft, connecting rod, intake valve 6, exhaust valve 14, spark plug or nozzle tip 7, is provided with left piston 5 and right piston 8 in the cylinder 4; Left piston 5 links to each other with left pitman shaft 15 on the left bent axle 1 through connecting rod; Right piston 8 links to each other with right connecting rod axle 12 on the right bent axle 9 through connecting rod, and cylinder 4 neutral positions are provided with intake valve 6 and exhaust valve 14, and spark plug or nozzle tip 7 are installed in intake valve 6 one sides; The first from left pitman shaft 2 links to each other with a right pitman shaft 10 through first long connecting rod 3; The second from left pitman shaft 16 links to each other with right two pitman shafts 11 through second long connecting rod 13, the equal in length of first long connecting rod 3 and second long connecting rod 13, and strictness links when guaranteeing that left bent axle 1 rotates by same direction with right bent axle 9; Know by Fig. 2; Owing to compare with traditional unidirectional power engine of doing, the direction of valve masthead valve has changed 90 degree, so in the position of intake valve 6 and exhaust valve 14 a valve stem conversion equipment 17 is installed respectively.
Said the first from left pitman shaft 2 differs 90 degree with the second from left pitman shaft 16 with respect to angle, left bent axle axle center, and a right pitman shaft 10 differs 90 degree with right two pitman shafts 11 with respect to angle, right bent axle axle center, does not have the rotation dead angle when rotating by same direction with right bent axle 9 to guarantee left bent axle 1.
Utilize the utility model principle also can make multicylinder engine.
