Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention does not receive the restriction of embodiment.
Extremely shown in Figure 3 like Fig. 1; The compressed air recovery equipment that engine braking of the present invention produces comprises energy recovery module 3, automatic energy distributor 4, one-way valve 8 and Gas Recovery pipeline 10; Automatically energy distributor 4 is installed in the energy recovery module 3, and energy recovery module 3 is on the current path between engine air inlet tube 7 and the cylinder head suction port 1.Suction tude 7, energy recovery module 3 and cylinder head are fixing through suction tude bolt 9, through energy recovery module pad 2 and 5 sealings of suction tude pad.Automatically energy distributor 4 is fixed on the energy recovery module 3 through automatic energy distributor fixing bolt 6, and bearing is through sealer 11 sealings.One-way valve 8 is connected with gas reclaim line 10 with energy recovery module 3 respectively through the screw thread at two ends.Every cylinder is installed an automatic energy distributor 4 and one-way valve 8.
During the motor proper functioning; The air inlet state is as shown in Figure 9: fresh air gets into the automatic energy distributor 4 of suction port 31 entering of suction tude 7 → through the energy recovery module; Automatically energy distributor 4 is in opening state (because one-way valve 8 cracking pressures are 0.5MPa; Suction pressure is less than 0.2MPa; Be fresh air when getting into, one-way valve 8 is closed) → fresh air gets into the energy recovery window 30 of energy recovery module 3 → and final first air outlet, 32 entering cylinder head suction ports 1 through the energy recovery module, is mixed for normal work by combustion with fuel oil.
During engine braking; It is shown in figure 10 to collect the pressurized gas working state: motor is in compressive state; Open intake valve through break; Pressurized air get into cylinder head suction port 1 → subsequently through first air outlet 32 get into energy recovery modules 3 → since automatically energy distributor 4 be one-way valve structures; Automatically energy distributor 4 was in closed condition → one-way valve 8 and opened (compressed air pressure is greater than the cracking pressure 0.5MPa of one-way valve 8, and one-way valve 8 is opened) this moment, and pressurized air gets into one-way valve 8 → finally get into the Gas Recovery pipeline and is used for compressed-air actuated recovery.
From above two kinds of working staties; Automatically (purpose that pressurized gas of the present invention reclaims is for the startup of giving motor source of the gas to be provided to energy distributor 4 at the air mixing power engine; Therefore be referred to as mixed power) on acting body present: at first; During the motor normal working, guarantee that enough fresh airs get into the cylinder head suction port through automatic energy distributor; Secondly, when collecting the pressurized gas working state, play seal action, make pressurized air not get back to suction tude, and get into the Gas Recovery pipeline through one-way valve 8 through automatic energy distributor.
Automatically the concrete structure of energy distributor 4 is like Fig. 4, shown in 5; Two the unidirectional valve seats (comprising the first unidirectional valve seat 12 and the second unidirectional valve seat 18 that are fixedly connected through two M3x25 screws 15) that comprise connection arranged side by side; Be symmetrical set two inclined-planes on each unidirectional valve seat; The lower end on each inclined-plane is through three M3x4 screw 19 clips (reed that wherein is positioned on the first unidirectional valve seat is first reed 14, and the reed that is positioned on the second unidirectional valve seat is second reed 17).Establish limiting board (limiting board comprises first limiting board 13 and second limiting board 16) between each unidirectional valve seat outside and two unidirectional valve seats, limiting board is used to prevent that the reed excessive deformation from causing fracture.When fresh air flowed into from two unidirectional valve seat bottoms, reed is backed down, and forms four air-flow paths, and was as shown in Figure 5; The pressurized air acting in opposition is when reed, and reed is close to and is used to block air-flow on the inclined-plane, in order to keep sealing during air-flow in blocking-up, can be on the inclined-plane outer wall, apply one deck caulking gum (not shown) with the reed contact position.
During the motor proper functioning, fresh air backs down four reeds under gas pressure, in Fig. 5, gets into cylinder head suction port 1 through automatic energy distributor 4 from the bottom to top; Collect when pneumatically operated, pressurized air acts on the reed, and reed is close on the caulking gum layer, and pressurized air can not get into suction tude through automatic energy distributor, can only get into the Gas Recovery pipelines through one-way valve 8.
The present invention is applied to the air mixing power engine with automatic energy distributor, and is installed in the energy recovery module, forms a work system with one-way valve and gas reclaim line, is used for the compressed-air actuated recovery that the engine cylinder cap suction port is discharged; The automatic energy distributor that relates to is combined through two unidirectional valve seats, realizes 4 air flow channels, with respect to two air flow channels of the prior art, and the circulation demand of fresh air in the time of more satisfying the motor proper functioning.
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.
