The invention discloses a kind of lubrication system for radial engine.For clarity sake, explanation is configured as the radial engine of the generator unit with relevant generator.Yet, will be appreciated that, disclosed improved lubrication system can use in various radial engine is used, such as but not limited to: other of Fixed Wing AirVehicle, rotary-wing aircraft, automobile, motorcycle, ships and light boats and radial engine use applicatory.In addition, disclosed lubrication system can be used in various orientation and configuration, such as but not limited to: vertical position, horizontal position and other various oblique position that is suitable for radial engine.

Improved lubrication system can comprise the outside supply of modified model and oil return/recirculating system, comprises the electronics lubricating pump of the lubricant feed pipeline that has a plurality of valves and enter radial engine is to guarantee it generally is instantaneous lubricant pressure.Lubricating pump can be used for to system perfusion and pressurization so that before starting and during starts provide oiling agent for swivel assembly.Can the in check lubricant cooler bypass valve of serviceability temperature in order to when starting, raise the efficiency and generate electricity.The external recirculation part can comprise at least one dump pump, is used for removing oiling agent in order to avoid pouring into cylinder from the inner region of radial engine after shutting down.

As hereinafter discussing in detail, lubricating pump directly is connected outside supply system with internal flow path in the swivel assembly.Specifically, flow path extends through bent axle from pump.Bent axle can connect (fluidly connected in through-flow body ground, perhaps be called " connection of fluid-phase earthing ") to master connecting rod (master connecting rod), this master connecting rod can be connected on each link rod (link rods) at the first end place by internal flow path through-flow body.The two includes the internal flow path that extends longitudinally that extends to the second end from first end master connecting rod and link rod.The second end is rotatably connected to the downside of piston by wrist pin.The second end also comprises the piston sprayer nozzle, and this piston sprayer nozzle provides increase and directed flowing to the downside of piston.

Pass lubricating pump and can form other flow path, it can be connected on the flow of lubricant road pipeline (lubricant galley lines) through-flow body.Flow of lubricant road pipeline is in the inside of crankcase, and provides the supply of lower pressure oiling agent to hydraulic tappet.Hydraulic tappet can be connected on the rocking arm by hollow push rod through-flow body.The two is sent to rocking arm from hydraulic tappet to hollow push rod with linear motion and oiling agent.Rocking arm forwards oiling agent on the moving parts in the rocker box to, and this rocker box is attached on the cylinder head, and this cylinder head is held gas handling system and vent systems and spark plug, and can be attached on the cylinder liner in order to form the firing chamber.Intake and exhaust system in the cylinder head comprises suction valve and outlet valve, and this suction valve and outlet valve can be by valve shaft Sealing and oiling agent isolation.Cylinder head also comprise a plurality of lubricant-return hole in case allow used flow of lubricant to adjacent cylinder assembly, flow to oil groove or flow to crankcase and the cam of gear-box and tappet side.Crankcase can Fluid Sealing at run duration, and transmits oiling agent by oiling agent pipeline and the lubricant passageway that can be connected at least one pump through-flow body.

At the run duration of radial engine, swivel assembly comprises bent axle, master connecting rod, link rod and piston.As mentioned above, oiling agent passes these part mobiles, and can discharge or be discharged in the crankcase.Along with swivel assembly rotation, oiling agent can upwards outwards be forced to the footpath by centrifugal force, this cause oiling agent to be stirred and be inflated to reach and will be interrupted or shear to oiling agent a bit, and cause overheated.Be used for reducing and stir and an element of inflation can be little louver, or flow-off, this little louver or flow-off inwardly stretch to swivel assembly and away from the wall that crankcase inner region and cam and the tappet side of crankcase are separated.

As following further discussion, flow-off work is so that oiling agent deflection, and oiling agent can flow by the flexing axle box, and it is drawn in the tappet zone.This effect can reduce wind disturbance (windage) and the aeration of oiling agent, can obtain better operational quality and operational condition like this, and reduces heating.Deflection and eliminating can make oiling agent carry out oil return by dump pump, and the flow path that outside oil return system is used for cooling, stores or be recycled to radial engine is pulled out and drawn in to this dump pump with oiling agent from crankcase.The eliminating of oiling agent can help to reduce the volume of oiling agent required in the crankcase, and is reduced in the possibility that overflow occurs in the lower cylinder.By forming bell housing from crankcase to this crankcase or the flow path of tappet side, each flow-off forms the other path that ventilates of being used for.In addition, by being recycled into through the oiling agent of cryogenic treatment in the process continuously, oiling agent can help prevent too early damage and prolong the life-span of swivel assembly.

In addition, when radial engine was shut down, the oil return of exterior lubricant processing system partly began the oiling agent of remainder is extracted out from the both sides of crankcase.This can accomplish to eliminate any remaining oiling agent guaranteeing that oil groove is done after shutting down, simultaneous minimization or eliminate any oiling agent and transfer to possibility in the firing chamber of the minimum cylinder in position.
