Abstract
The invention discloses a cylinder mechanism with a suspension piston, which comprises a cylinder body and the piston, wherein the piston is in clearance fit with an inner wall of the cylinder body so that the gap of 0.2-0.5mm between the piston and the inner wall of the cylinder body is guaranteed. The cylinder mechanism with the suspension piston further comprises a sealed piston box, the piston box is in butt joint and in sealing connection with the cylinder body, a back-filling pipeline is installed on the side of the piston box, a booster pump and a check valve are arranged on the back-filling pipeline, and the other end of the back-filling pipeline is connected to a side wall of the cylinder body and penetrates through the side wall of the cylinder body to be communicated with the inside of the cylinder body. The cylinder mechanism with the suspension piston has the advantages that leaked gas can be filled back into the cylinder body through the sealed piston box and the back-filling pipeline, and the problems of environmental pollution caused by the fact that the suspension piston leaks gas and the damage to an engine are solved.
Description
Technical field
The present invention relates to a kind of cylinder piston mechanism, belong to the power system engine art.
Background technique
As everyone knows, the cylinder piston mechanism of existing technology has seal ring to seal on the surface of piston, and over more than 100 year, such structure is always in occupation of the main flow cylinder piston mechanism of market engine.But in the combustion chambers burn process of field of internal combustion engine, can produce high temperature and high pressure gas, can be heated between cylinder and the piston, rub, be present main flow motor manufacturer subject matter to be solved so how to improve the wear resistance at elevated temperature of cylinder piston.
Also have some cylinder piston mechanisms to adopt the mode of suspended piston to be provided with; But owing to suspended piston is easy to generate the power that gas leakage reduces motor; And the gas that spills just is discharged in the atmosphere without handling; Also pollute the environment, the existence of these gases in motor also can make the life-span of motor descend.
The present invention is directed against the improvement that the engine air cylinder structure of suspended piston carries out, and solves the problem of the engine apparatus gas leakage of suspended piston.
Summary of the invention
The objective of the invention is to solve the problem of existing cylinder piston mechanism gas leakage, a kind of suspended piston cylinder mechanism is provided.
The objective of the invention is to realize through following technological scheme:
The suspended piston cylinder mechanism comprises cylinder block and piston, adopts Spielpassung between the inwall of said piston and cylinder block; The space of 0.2-0.5mm between the inwall of assurance piston and cylinder block; Said suspended piston cylinder mechanism also comprises airtight piston case, and said piston case docks with said cylinder block and is tightly connected, and is equipped with one in the side of said piston case and recharges pipeline; The said pipeline that recharges is provided with suction booster and one-way valve; The said the other end that recharges pipeline is connected on the sidewall of cylinder block, and passes the sidewall and the cylinder block internal communication of cylinder block, the said position that the position is lower than the sidewall of said piston top dead center corresponding cylinder body that is communicated with that recharges pipeline and cylinder block; Can guarantee like this piston compress and two strokes that explode in, avoid recharging pipeline and bear big pressure.
The invention has the beneficial effects as follows, through airtight piston case with recharge in the cylinder block that pipeline can recharge the gas of revealing the problem of having avoided suspended piston gas leakage befouling environment and motor having been brought damage; And the said pipeline that recharges is connected to the cylinder block corresponding position below the top dead center, and can avoid recharging pipeline and bear higher calming the anger and the stroke pressure that explodes, piston pressure to cylinder interior in descending process is compensated.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the structural drawing of the described suspended piston cylinder mechanism of the embodiment of the invention.
Embodiment
As shown in Figure 1; The described suspended piston cylinder mechanism of the embodiment of the invention comprises cylinder block 1 and piston 2, adopts Spielpassung between the inwall of said piston 2 and cylinder block 1; The space of 0.2-0.5mm between the inwall of assurance piston 2 and cylinder block 1; Said suspended piston cylinder mechanism also comprises airtight piston case 3, and said piston case 3 docks with said cylinder block 1 and is tightly connected, and is equipped with one in the side of said piston case 3 and recharges pipeline 4; The said pipeline 4 that recharges is provided with suction booster 5 and one-way valve 6; The said the other end that recharges pipeline 4 is connected on the sidewall of cylinder block 1, and passes the sidewall and cylinder block 1 internal communication of cylinder block 1, the said position that the position is lower than the sidewall of said piston top dead center corresponding cylinder body 1 that is communicated with that recharges pipeline 4 and cylinder block 1; Can guarantee like this piston compress and two strokes that explode in, avoid recharging pipeline and bear big pressure.
The invention has the beneficial effects as follows, through airtight piston case with recharge in the cylinder block that pipeline can recharge the gas of revealing the problem of having avoided suspended piston gas leakage befouling environment and motor having been brought damage; And the said pipeline that recharges is connected to the cylinder block corresponding position below the top dead center, and can avoid recharging pipeline and bear higher calming the anger and the stroke pressure that explodes, piston pressure to cylinder interior in descending process is compensated.
