Electronic control type Cylinder lubricating device 20 of the present invention forms to such an extent that have: described injector 12a～12n and each sensor 13a～13n; The lubricating pump that Fig. 1 represents (back slightly is called pump) 14; Send oil pipe 15 jointly as what send oily portion jointly; A plurality of forks send oil pipe 16a～16n; A plurality of electromagnetic opening and closing valves (back slightly is called solenoid valve) 17a～17n; A plurality of oil mass limiter 18a～18n; The control gear 19 of piezoelectricity minor.
The rotation of the electronic or engine revolution portion of transmission and driven pump 14 for example can use appropriately that to flow be unidirectional constant volume type oil pressure pump.Send oil pipe 15 connections jointly on the exhaust port of the pump 14 of removal of lubricant (also being cylinder oil).Send oil pipe 15 along the configuration of each cylinder 11a～11n of motor pipe arrangement back and forth jointly.This send the internal capacity of oil pipe 15 in order to have regulation as total circuit functions jointly, can keep being stored in its inside with the pressurized state that authorized pressure keeps from the lubricant oil of pump 14 force feeds.Send oil pipe 15 to be configured on all cylinder 11a～11n jointly, it is last or for example be configured on a plurality of cylinders of every adjacency instead, also can be arranged on each each cylinder 11a～11n.
Each fork send oil pipe 16a～16n to be arranged to each each cylinder 11a～11n and goes up the same quantity of injector 12a～12n that is provided with.These forks send the end of oil pipe 16a～16n to be connected to and send jointly on the oil pipe 15, and it is last so that the lubricant oil guiding is imported path to described oil that the other end is connected injector 12a～12n one by one.
Each oil mass limiter 18a～18n possesses housing 31, guiding valve 32 and as the helical spring 33 of pressured body in detail.
Become in the housing 31 cylindraceous, the transparency window 31c that is formed with ring-type is set between first, second casing member 31a and 31b, have appreciable grease chamber 34 by transparency window 31c.Can see guiding valve 32 in the housing 31 by transparency window 31c, so be suitable for using as required the action of visual surveillance guiding valve 32.
The first casing member 31a has oil-in 35, and this oil-in is communicated with grease chamber 34 and is quite little footpaths than the footpath of this grease chamber 34.This oil-in 35 is communicated with to be sent on the oil pipe 15 jointly.The second casing member 31b has oil export 36, and this oil export is communicated with grease chamber 34 and is quite little footpaths than the footpath of this grease chamber 34.This oil export 36 is communicated with on injector 12a～12n some by corresponding solenoid valve 17a～17n some.34 part forms the valve seat 36a of taper to oil export 36 towards the grease chamber.
Be equipped with on each of each oil mass limiter 18a～18n as desirable example and detect the rising sensor 38 that guiding valve 32 moves.Can use the magnetic quantity transducer of non-contact type etc. on this sensor 38 rightly.Rising sensor 38 for example detects the shoulder 32c of guiding valve 32.This shoulder 32c remains on oil-in 35 primary importance (state of Fig. 4) on one side at guiding valve 32 from pushing with the power of helical spring 33, because oil pressure and be close to the second place on valve seat 36a when moving to the front end 32a of path one side of guiding valve 32 detects with rising sensor 38.The testing signal of each sensor 38 that rises is input to control gear 19.
Making such as control gear 19 usefulness microcomputers are driven valve constantly and keep opening valve time each carries out the same period or noncontemporaneous control according to various inputs to the running of pump 14 and solenoid valve 17a～17n.Except the testing signal of each rising sensor 38, can also enumerate the detected temperatures (temperature cylinder signal) of each sensor 13a～13n shown in Figure 1, the crankshaft angles signal of motor and the load signal of motor etc. to the input of control gear 19.
The crankshaft angles signal detects with crankshaft angles detection device 39.This detection device 39 is made of the contactless switch that is located at detected portion such as projection on the engine crankshaft and magnet and detects it, for example to one week of crankshaft rotating produce the detection pulse (with reference to Fig. 3) of one or many, its apparatus for controlling of supply 19.The load signal of motor is made of engine loading calculation portion 40, this calculation portion 40 from the crankshaft angles signal obtain the rotation number of bent axle, the load of calculating motor according to this rotation number is high capacity or low load.The output of this calculation portion 40 (engine loading signal) apparatus for controlling of supply 19.
The following describes oiling action to cylinder 11a～11n.The crankshaft angles signal that detects by engine-driving, crankshaft angles detection device 39 gives control gear 19.Thereupon the moment sky that improves from the crankshaft angles signal of control gear 19 open reasonable time t1 (with reference to Fig. 3) again each solenoid valve 17a～17n excitation, make these solenoid valves 17a～17n become out the valve state, keep the excitation of cutting off solenoid valve 17a～17n behind the valve state of opening of appropriate time from this moment, become the valve state that closes.
Become out the valve state by such telecontrol, solenoid valve 17a～17n, the lubricant oil that in accordance with regulations pressure state stores in sending oil pipe 15 jointly send oil pipe 16a～16n to be directed into to be connected one by one these to send in injector 12a～12n on oil pipe 16a～16n by each fork.Front end from each injector 12a～12n sprays, carries out oiling to lubricant oil in cylinder 11a～11n like this.This oiling becomes by solenoid valve 17a～17n closes the valve state and stops.Control gear 19 by change solenoid valve 17a～17n begin promptly to keep opening valve time t2 (with reference to Fig. 3) and can adjust oil filling amount from driving valve to closing time that valve ends.
As above, the control gear 19 of electronic type is opening the valve moment and keeping opening valve time of benchmark telecontrol solenoid valve 17a～17n with the crank shaft angle testing signal to its input, so the on-off action of solenoid valve 17a～17n is carried out in the motion that can meet the piston that is moved by engine crankshaft in good time, can the suitable moment the oiling in cylinder 11a～11n of the lubricant oil of appropriate amount.
At this moment each oil mass limiter 18a～18n is situated between, and being contained in respectively diverges send on oil pipe 16a～16n.Feed through to the oil pressure of the throttling arrangement path 37 of guiding valve 32 like this by oil-in 35 by oil mass limiter 18a～18n, and guiding valve 32 is moved to oil export 36 directions, soon the front end 32a of path one side of guiding valve 32 is close on the valve seat 36a of oil export 36, and oiling is limited from this moment.
But to the lubricant oil of cylinder 11a～11n injection is instinct lubricant oil grease chamber 34 in along with these guiding valve 32 compressions of mobile usefulness of above guiding valve 32, and control gear 19 control described time t1, t2 were over oiling before the oil mass restriction begins.Therefore oil mass limiter 18a～18n can not hinder oiling.When solenoid valve 17a～17n closes, when lubricant oil does not flow, guiding valve 32 is pushed back by helical spring 33, at this moment the lubricant oil throughput of grease chamber 34 is a spot of to throttling arrangement path 37, so guiding valve 32 is pushed back lentamente.
Therefore according to the signal level of the engine loading signal of input, from the control gear predefined engine loading of 19 memory portions and oil filling amount concern the loading liquifier of defined, read the value of only oil filling amount, can change and keep opening valve time t2 and become this oil filling amount.The load of motor can increase to oil filling amount of cylinder 11a～11n etc. more greatly more, can carry out suitable oiling according to engine loading like this.
And control gear 19 has been imported the temperature cylinder signal of a plurality of temperature transducer 13a～13n detection that is installed in respectively on cylinder 11a～11n, so with this temperature signal be benchmark, control gear 19 each solenoid valve 17a～17n each keep opening valve time t2 telecontrol one by one, can change the oil filling amount of spraying one by one from each injector 12a～12n.
The temperature conditions of each one of cylinder that has been the temperature cylinder signal indication, so to detect the temperature part higher than other parts, according to the signal level of the temperature cylinder signal of control gear 19 input, from the control gear predefined temperature cylinder of 19 memory portions and oil filling amount concern the thermometer of defined, read the value of only oil filling amount, can change and keep opening valve time t2 and satisfy this oil filling amount.
Like this to the injector that is positioned at the high part of temperature cylinder supply with the lubricant oil of Duoing than other injectors, can be to Cylinder lubricating.The part of general lack of lubrication produces frictional heat, temperature too rises, and consideration might produce burn.To this as described in, according to the temperature of each one of cylinder, increase the corresponding oil filling amount that is positioned at the injector of cylinder high-temperature part by the opening valve time t2 that keeps with the corresponding solenoid valve of control gear 19 telecontrol, can be according to the temperature oiling suitably of each one of cylinder.
As mentioned above, oil mass limiter 18a～18n is arranged on each fork one by one and send on each of oil pipe 16a～16n, when so any generation fault of solenoid valve 17a～17n stops opening the valve state, connect the oil mass limiter that is provided with this solenoid valve by the oil pressure from sending oil pipe 5 to involve jointly, make guiding valve 32 move to the oil export 36 that the second place is promptly stopped up housing 31.Can prevent to send jointly the extreme pressure lubricant that stores in the oil pipe 15 by the oiling excessively of out of order solenoid valve like this, the reliability of oiling action is good.Lubricant oil by its throttling arrangement path 37 when guiding valve 32 is configured in the second place is current, but this discharge is a spot of, so there is not substantial problem.
And each oil mass limiter 18a～18n possesses and detects the rising sensor 38 that guiding valve 32 moves, and is input to control gear 19 from the testing signal of these rising sensor 38 outputs.Therefore control gear 19 can with its guiding valve judgement section judges for example guiding valve 32 can automatically monitor like this that whether rightly moving whether solenoid valve 17a～17n is in proper function.Control gear 19 can be calculated the amount of movement of guiding valve 32 with its guiding valve amount of movement portion of calculating in addition.Can also calculate the result to this like this uses as the control oil filling amount feedback signal for moment of obtaining closing solenoid valve 17a～17n.Control gear 19 is obtaining can utilizing the signal of rising sensor 38 to monitoring the various purposes such as useful signal of oiling situation and control oiling in order to reach by possessing the guiding valve judging part and the guiding valve amount of movement is calculated various processing divisions such as portion.
As above, Cylinder lubricating device 20 in the action of motor also can with telecontrol change solenoid valve 17a～17n open valve constantly, in cylinder 11a～11n with appropriate moment oiling, and can change keeping opening valve time t2, adjusting from the oil filling amount of injector 12a～12n in cylinder 11a～11n etc. of solenoid valve 17a～17n with telecontrol, oiling controlled good.
The Cylinder lubricating device 20 of described structure comprise send jointly oil pipe 15 and each fork send oil pipe 16a～16n send oil system to be provided in back and forth to be installed on injector 12a～12n on pump 14 and each cylinder 11a～11n of motor.Therefore not resembling when using mechanical type Cylinder lubricating machine of the prior art, not only need to use numerous and diverse connect hours of shaft joint but also the time that needs are aimed at the axle center, the pipe arrangement system by back and forth can be 20 pairs of motors of Cylinder lubricating device easily and setting at low cost.
