Combine Figure 10-13 to further describe the working procedure of paraffin temp controller 200 of the present invention now.Paraffin temp controller 200 with the paraffin 205 that held in its red copper seat as temperature-sensing element; It utilizes the characteristic of expanding with heat and contract with cold of paraffin 205 to promote push rod 202 and moves; Thereby the jut of falling the arrow-shaped 212 that makes push rod 202 is opened or the connecting passage of closed vent hole 208 and measuring room 33, thus the oil spout of control motor main nozzle 20 in the measuring room when starting.According to paraffin controller 200 of the present invention; Its configurable one-tenth is when temperature is lower than first temperature threshold; The push rod 202 of paraffin temp controller 200 is in closed condition; And when temperature was higher than second temperature threshold, the push rod 202 of paraffin temp controller 200 was in open mode, and is concrete like Figure 12 and shown in Figure 13.In an exemplary embodiment; First temperature threshold of the present invention is set at for example 20 °; And second temperature threshold is set at for example 38 °, and according to the different application occasion of motor, first temperature threshold of the present invention or second temperature threshold can change; For example first temperature threshold can be set at the arbitrary temp value between 18 ° to 25 °, and second temperature threshold can be set at the arbitrary temp value between 35 ° to 42 °.
Be in low-temperature condition at motor, when for example ambient temperature is lower than 20 ° first temperature threshold, if pilot engine; Need with hand extrusion pump oil ball 7; Promote Air strangler spindle 3 rotations by the spiral chute on the spiral cell body 68, the closure transmission arm on the Air strangler spindle 3 60 promotes chock plate transmission arm 50 then, makes linking mechanism be in linkage status; The flat place 341 of milling on the Air strangler spindle 3 connects the pulse 37 of motor with the measuring room 33 of Carburetor at this moment, sees Fig. 9.After pulse 37 got in the measuring room 33, pulsation promoted the metering diaphragm 2110 in the measuring room 33.Because the push rod 202 of paraffin temp controller 200 is in closed condition at this moment; Vent 208 not with atmosphere; Impulsive force is directly extruded the fuel oil 103 in the measuring room 33 from main nozzle 20; Because the fuel oil that extrude from main nozzle 20 this moment forms dense air and fuel mixture in mixing chamber 101, thereby is convenient to the starting of motor.
When motor at high temperature starts, when for example ambient temperature is higher than 38 ° second temperature threshold, if pilot engine; At first use hand extrusion pump oil ball 7; Likewise under the promotion of spiral chute 8, Air strangler spindle 3 rotates, and the closure transmission arm 60 that drives then on the Air strangler spindle 3 is rotated counterclockwise; Thereby promoting closure transmission arm 50 turns clockwise; Make linking mechanism be in linkage status, as shown in Figure 6, this moment, the flat place 341 of milling of Air strangler spindle 3 connected the pulse 37 of motor with measuring room 33.Because paraffin temp controller 200 is under the effect of paraffin 205; Promote push rod 202; Push rod 202 overcomes the tension force of return spring 209; The jut of falling the arrow-shaped of push rod 212 leaves the shoulder seat 215 on the main body 203, and push rod 202 is in open mode, makes push rod chamber 211 through vent 208 and atmosphere.At this moment; Even the pulse 37 that gets in the measuring room 33 can promote to measure diaphragm 2110; But because vent 208 and atmosphere, the power that acts on the metering diaphragm 2110 can be little a lot, therefore measure diaphragm 2110 and can not more fuel oil be extruded from main nozzle 20; Can only extrude a spot of fuel oil, see Figure 13.At this moment, the fuel oil that sprays during through aditus laryngis 104 is less, and formed mixture strength is still not high in mixing chamber 101, and this has just realized the less fuel demand of piloting engine under the high temperature, thereby satisfies the starting demand under the engine high-temperature.
With reference to Figure 14, Figure 14 is the oil circuit figure of the needle-valve system on the main body among Fig. 1 at last.This needle-valve system comprises pintle valve seat 40, needle-valve 41, needle-valve Rocker arm 42, metering spring (not shown), metering diaphragm 2110, sealing paper washer 43.Carburetor through extrusion pump oil ball 7, produces vacuum (suction) at prestart in pump oil ball 7, then with fuel oil sucking-off from oil can, get in the oil inlet pipe 18 of Carburetor again.Fuel oil gets in the oil inlet pipe 18, gets into loam cake 14, from the oil-feed oil circuit of loam cake 14, through in the laggard oil circuit of going into main body 1, gets in the needle-valve system of Carburetor shown in Figure 14 again.When fuel oil gets into the needle-valve system; Get into measuring room 33 through pintle valve seat 40, needle-valve 41; Fuel oil parts in the measuring room 33 get in the pump oil ball 7 again, and unnecessary fuel oil is got back to oil can from the outlet of pump oil ball 7, when the fuel oil of a part is stayed in the measuring room 33 as engine operation with oil.Because the effect of metering spring is arranged, the fuel oil in the measuring room 33 of Carburetor reaches a certain amount of back under the effect of metering spring, and needle-valve 41 is closed, and unnecessary fuel oil can not get in the measuring room 33.Otherwise, the fuel oil in measuring room 33 by motor from main nozzle 20 sucking-offs (seeing Figure 11), few after to a certain degree; Under the effect of motor vacuum; Metering diaphragm 2110 promotes needle-valve Rocker arm 42, drives needle-valve 41 by needle-valve Rocker arm 42 again, and needle-valve 41 is opened; New fuel oil gets into measuring room, satisfies the need of work of motor.
Although at length disclose the present invention, should be understood that these descriptions only are exemplary, are not to be used for limiting application of the present invention with reference to accompanying drawing.Protection scope of the present invention is limited accessory claim, and can be included under the situation that does not break away from protection domain of the present invention and spirit various modification, remodeling and equivalents to the present invention did.
