Abstract
The invention discloses a suspension piston type cylinder component, which comprises a cylinder, a piston and a closed crankcase. The crankcase is in butt joint and sealed with the cylinder, the piston is in clearance fit with the inner wall of the cylinder, the cylinder is in sliding seal with the piston without a sealing ring, a gas recharge pipeline is connected onto a side wall of the crankcase, is connected onto the cylinder and corresponds the position below a top dead center of the piston, a cooling liquid inlet is arranged on a side wall of the cylinder and communicated with a high-pressure cooling liquid container via a channel, a control valve is disposed on the channel, and the cooling liquid inlet is positioned on the side wall of the cylinder and corresponds to an area between the top dead center and a bottom dead center of the piston. The suspension piston type cylinder component has the advantages that leaking gas of the suspension piston can be recharged into the cylinder via the gas recharge pipeline without leaking to the outside of a closed space encircled by the cylinder and the crankcase, so that burning high-pressure gas is sufficiently utilized assuredly.
Description
Technical field
The present invention relates to a kind of suspended piston formula cylinder assembly, belong to the power system engine art.
Background technique
As everyone knows; Cylinder and piston in the existing cylinder piston mechanism all are sealed and matched; The outer installment of piston has 3-5 ring seal ring, and seal ring cooperates sliding contact with the inner wall sealing of cylinder, piston is slided in cylinder in the gas of maintenance cylinder interior can not reveal away.But cylinder piston mechanism is in high temperature, and each item performance of metal all can descend, and comprises the rub resistance ability, and obviously this can cause cylinder piston mechanism bigger in the condition lower cylinder inner wall abrasion of high temperature.
Summary of the invention
The objective of the invention is to solve existing technology cylinder piston mechanism under high temperature condition, wear resistance decrease, and then cause the problem of the inner wall abrasion of cylinder, a kind of suspended piston formula cylinder assembly is provided.
The objective of the invention is to realize through following technological scheme:
Suspended piston formula cylinder assembly; Comprise cylinder, piston and airtight crankcase; Said crankcase docks and seals with cylinder; Seal ring is not set between Spielpassung and cylinder and the piston between the inwall of said piston and cylinder carries out slipper seal, connect a gas on the sidewall of said crankcase and recharge pipeline, said gas recharges pipeline and is connected to the position below the corresponding piston top dead center on the cylinder; On the sidewall of cylinder, have cooling fluid inlet; Said cooling fluid inlet and high pressure cooling fluid container is communicated with and on passage, is provided with control valve; Said cooling fluid inlet perhaps can further recharge the pipeline one with said cooling fluid inlet and said gas and be connected on the cylinder sidewall of institute corresponding region between piston top dead center and the lower dead center.
The invention has the beneficial effects as follows; The gas that suspended piston that the present invention designed leaks can pass through gas and recharge pipeline and recharge cylinder interior; The gas of revealing can not leak into the outside of the confined space that cylinder and crankcase surround, and guarantees that the pressurized gas that burn are fully utilized; And the cooling fluid inlet on the cylinder sidewall; Can pour cooling liquid to the space between cylinder and the piston; Cooling liquid can play lubricated effect on the one hand, and cooling liquid can become gas after being heated on the other hand, is full of in the space between cylinder and piston; Reach the effect of gas barrier, can prevent to carry out between cylinder and the piston direct contact friction.
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 formula of embodiment of the invention cylinder assembly.
Embodiment
As shown in Figure 1; The described suspended piston formula of embodiment of the invention cylinder assembly; Comprise cylinder 1, piston 2 and airtight crankcase 3, said crankcase 3 docks and seals with cylinder 1, between Spielpassung and cylinder 1 and the piston 2 seal ring is not set between the inwall of said piston 2 and cylinder 1 and carries out slipper seal; Connect a gas on the sidewall of said crankcase 3 and recharge pipeline 4, said gas recharges pipeline 4 and is connected to the position below the corresponding piston top dead center on the cylinder 1; On the sidewall of cylinder 1, have cooling fluid inlet 5; Said cooling fluid inlet 5 and high pressure cooling fluid container 6 is communicated with and on passage, is provided with control valve; Said cooling fluid inlet 5 perhaps can further recharge pipeline 4 one with said cooling fluid inlet 5 and said gas and be connected on the cylinder sidewall of institute corresponding region between piston top dead center and the lower dead center.
The invention has the beneficial effects as follows; The gas that suspended piston that the present invention designed leaks can pass through gas and recharge pipeline and recharge cylinder interior; The gas of revealing can not leak into the outside of the confined space that cylinder and crankcase surround, and guarantees that the pressurized gas that burn are fully utilized; And the cooling fluid inlet on the cylinder sidewall; Can pour cooling liquid to the space between cylinder and the piston; Cooling liquid can play lubricated effect on the one hand, and cooling liquid can become gas after being heated on the other hand, is full of in the space between cylinder and piston; Reach the effect of gas barrier, can prevent to carry out between cylinder and the piston direct contact friction.
Claims (2)
1. suspended piston formula cylinder assembly; Comprise cylinder, piston and airtight crankcase; It is characterized in that said crankcase docks and seals with cylinder, seal ring is not set between Spielpassung and cylinder and the piston between the inwall of said piston and cylinder carries out slipper seal; Connect a gas on the sidewall of said crankcase and recharge pipeline, said gas recharges pipeline and is connected to the position below the corresponding piston top dead center on the cylinder; On the sidewall of cylinder, have cooling fluid inlet, said cooling fluid inlet is communicated with high pressure cooling fluid container and on passage, is provided with control valve, and said cooling fluid inlet is on the cylinder sidewall of institute corresponding region between piston top dead center and the lower dead center.
