Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention is described in detail, but is to be understood that protection scope of the present invention does not receive the restriction of embodiment.
As shown in Figure 1, this gas starting motor comprises: engine body 1; Brake assembly 2 as braking force control system, is used to control the switching of the suction valve 101 in the said engine body 1 and then engine body 1 is braked control; Energy recovery module 3 and with this energy recovery module 3 through the gas cylinder that Gas Recovery pipeline assembly 7 is communicated with, be used for collecting and store engine body 1 at pressurized gas that braking process produced; Pneumatic motor 10 is Pneumatic actuator, the pressurized air that is used for using gas cylinder 8 as driving source with ato unit body 1.
As shown in Figure 2; Brake assembly 2 comprises brake casing 14, on brake casing, through adjusting screw 12 and nut 13 driven plunger assembly 17 is installed, and on driven plunger assembly 17, is provided with draining pin 16; Above draining pin 16, be provided with ring washer 15; In driven plunger assembly 17, be provided with filter screen folder 20 and filter screen 21, be connected with spring sheet 18 and bolt 19, through pressing plate 27 and bolt 28 solenoid valve 26 is installed at brake casing 14 at driven plunger assembly 17; On the surface of contact of solenoid valve 26 and brake casing 14, be provided with O RunddichtringO 22,23,24, be used for enhanced leaktightness property.Also be provided with filter screen 25 at solenoid valve 26.
As shown in Figure 3, the brake casing 14 of brake assembly is installed on the pitman arm shaft bearing of motor, is assemblied on the cylinder cap fastening with bolt with said pitman arm shaft bearing.Be provided with oil circuit in the said brake casing 14, solenoid valve 26 is electrically connected and is installed in Engine ECU on the oil circuit in the brake casing 14.Each driven plunger assembly 17 on the housing 14 is arranged at each engine air raft of pontoons top accordingly.Said solenoid valve is controlled the flow direction and the pressure of oil circuit in the housing under the signal that ECU sends, under the effect of the oil pressure of housing oil circuit, this driven plunger assembly 17 can carry out the motion of above-below direction.
The braking process of motor is: when motor is in compressive state; Solenoid valve in the brake assembly is opened oil circuit under the control of Engine ECU; Driven plunger assembly 17 is moved downward; The bottom surface of driven plunger assembly applies downward pressure to the contact platform of the air valve bridge on the inlet valve rocker, drives suction valve 101 and opens, and the pressurized air in the cylinder is discharged from the gap of intake valve; Thereby engine body 1 is done the braking that negative work realizes motor, and the pressurized air of discharging simultaneously is recyclable to be utilized again.
Like Fig. 4, shown in 5, between the suction port 30 of engine air inlet tube 7 and cylinder head, energy recovery module 3 is installed.As shown in Figure 5, this energy recovery module 3 is the cavity that an inside is equipped with energy distributor 5, and said energy distributor 5 is a unidirectional air pressure valve, and air can only enter into cylinder head suction port 30 through energy distributor 5 from suction tude assembly 4.The cavity of said energy recovery module 3 communicates with gas cylinder 8 through Gas Recovery pipeline assembly 7, and the first unidirectional air pressure valve 61 is installed on the Gas Recovery pipeline assembly 7.With reference to figure 1, in the engine braking process, the pressurized gas of discharging from intake valve is collected to gas cylinder 8 from energy recovery module 3 through Gas Recovery pipeline assembly 7.Two gas ports of gas cylinder 8 are separately installed with second Non-return air valve 62 and the 3rd Non-return air valve 63.Said energy distributor 5 and first Non-return air valve 61, second Non-return air valve 62 and the 3rd Non-return air valve 63 are used for preventing the backflow of collection of energy process pressurized gas.The energy recovery principle is as shown in Figure 7; During the motor proper functioning (shown in Fig. 7-1); Fresh air gets into the suction port 31 of energy recovery module from suction tude 4; Energy distributor 5 is an one-way valve, and this moment, this one-way valve was opened, and since this moment fresh air underpressure to open first one-way valve 61 (the first one-way valve cracking pressure is 0.5MPa); Therefore fresh air directly gets into cylinder head suction port 30 from the air outlet 32 of energy recovery module 3, and motor is realized the air inlet state of proper functioning; During engine braking; Pressurized air is back to the air outlet 32 of energy recovery module from cylinder head suction port 30; Energy distributor this moment (being one-way valve) is closed; And because compressed-air actuated pressure is greater than the cracking pressure of first one-way valve 61 at this moment, first one-way valve 61 is opened, and pressurized air gets into Gas Recovery pipeline 7 and gets into gas cylinder 8 and reclaims.
As shown in Figure 6, pneumatic motor 10 is connected with gas cylinder 8 through three pipelines.Article one, be provided with starting control valve in the pipeline, this pipeline is used for to the engaging gear of pneumatic motor 10 power being provided, and when connecting this pipeline, under the effect of pressurized gas, engaging gear moves forward to the flywheel ring gear engagement with engine body 1.Second pipeline is provided with main starter gate valve, and this pipeline is used for to the rotation of the rotatingshaft of pneumatic motor 10 power being provided, and when connecting this pipeline, under the effect of pressurized gas, thereby the rotation of the rotatingshaft of pneumatic motor 10 drives engine start.The 3rd pipeline is used to reclaim residual air; Behind engine start; Close first pipeline and second pipeline; Pneumatic motor 10 stops the rotation, and the engaging gear of pneumatic motor 10 bounces back to the flywheel ring gear of engine body 1 and separate, and remaining pressurized gas is back to gas cylinder 8 through the 3rd pipeline in the pneumatic motor 10.
Compared with prior art; The present invention is through the pressurized air that reclaims motor and in braking process, produced and with its driving source as pneumatic motor; Promptly practiced thrift the energy, avoided again producing in the existing technology the noise that pressurized air produced, energy-conservation and environmental protection.
More than disclosedly be merely a specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
