Abstract
The invention relates to a fuel and slide oil radiator structure. The structure comprises a shell, a heat exchange structure, a slide oil inlet valve, a slide oil outlet valve and a fuel oil inlet valve. A fuel oil path and a slide oil path are arranged in the shell, branch oil paths are arranged at the position, behind the slide oil inlet valve, of the slide oil path, one path flows through the heat exchange structure and is connected with a slide oil outlet, the other path passes through the slide oil outlet valve and then is s connected with the slide oil outlet, branch oil paths are arranged on a fuel oil inlet oil path of the fuel oil path, one path flows through the heat exchange structure and is connected with a fuel oil outlet, and the other path passes through the fuel oil inlet valve and then is connected with the fuel oil outlet. The fuel and slide oil radiator structure is simple and compact, obvious in use effect and capable of being widely applied to design of fuel and slide oil radiator structures and ensures normal use of an engine and flying safety.
Description
Technical field
The present invention relates to a kind of combustion oil cooler structure.
Background technique
In small aero, need to design a kind of combustion lubricating oil exchange sink, this combustion oil cooler need access fuel pump by fuel oil, by inflow combustion oil cooler and lubricating oil after supercharging, completes heat exchange; Meanwhile, need to outside radiator, design separately a check valve, to prevent that lubricating oil enters engine interior when motor is parked, structure is comparatively complicated, and the volume of whole motor and quality are strengthened.In addition, sometimes, because combustion lubricating oil impurity is more, can cause radiator surprisingly to stop up, oil circuit is not freely blocked even completely, not only do not realize normal heat exchange requirement, also can cause each parts of motor to can not get normal fuel feeding, motor cannot normally be worked, even cause the generation of accident.
Summary of the invention
The object of the invention is to design a kind of simple in structure, when can realize heat exchange, in the time of also can preventing that motor from parking, lubricating oil enters engine interior; Meanwhile, when radiator surprisingly stops up, can, to the normal fuel feeding of each parts of motor, ensure flight safety.
Technological scheme of the present invention is that combustion oil cooler structure comprises housing, heat exchange structure, lubricating oil inlet valve, lubricating oil outlet valve, fuel inlet valve, is provided with fuel path and lubricating oil oil circuit in housing; On lubricating oil import oil circuit, be provided with lubricating oil inlet valve, be provided with branch's oil circuit on the oil circuit after lubricating oil inlet valve, road heat exchange structure and the lubricating oil outlet of flowing through is connected, after the lubricating oil outlet valve of another road through arranging, exports and is connected with lubricating oil; On the fuel inlet oil circuit of described fuel path, be provided with branch's oil circuit, the road heat exchange structure of flowing through is connected with fuel outlet, and another road is connected with fuel outlet after fuel inlet valve; Described lubricating oil inlet valve, lubricating oil outlet valve, fuel inlet valve are check valve.
When the present invention works, high pressure lubricating oil, by pressure, is opened lubricating oil inlet valve, and lubricating oil enters after combustion oil cooler, after heat exchange, directly flows out; Fuel oil directly enters radiator, after heat exchange, directly flows out; And when radiator stops up, fuel oil and lubricating oil pressure continue to increase, high pressure lubricating oil is opened lubricating oil outlet valve, lubricating oil is without radiator, and directly from branch's oil circuit, flow out, and high pressure fuel is opened fuel inlet valve, fuel oil is without radiator, also be directly from branch's oil circuit, to flow out, therefore guaranteed the normal fuel injection needs of body.When motor is not worked, lubricating oil exists without pressure, and lubricating oil inlet valve is not opened, and has also stoped lubricating oil to enter engine interior.
The valve design of the present invention's lubricating oil inflow engine when preventing from not working, on the oil circuit of radiator,, combines fuel oil oil-feed oil circuit meanwhile with firing oil cooler, reduced volume and the quality of motor.The lubricating oil outlet valve and the fuel inlet valve that on oil circuit, increase, when radiator is stopped up, can guarantee the fuel feeding demand of motor each several part.The present invention is simple and compact for structure, and using effect is obvious, has guaranteed the normal use of motor and flight safety, and can be widely used in firing in oil cooler structural design.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
