In view of this, the utility model provides a kind of horizontal piston, to realize solution horizontal outside piston upper side lubricant oil, forms difficult problem; The utility model also provides a kind of horizontal internal combustion engine.
In order to achieve the above object, the utility model provides following technological scheme:
A piston, its inside is provided with oil duct in piston, is provided with the drainback passage that is communicated with described oil duct in piston on the cylindrical upper side of described horizontal piston.
Preferably, in above-mentioned horizontal piston, between the cylindrical upper side of described horizontal piston and described oil duct in piston, be provided with a plurality of described drainback passage that is communicated with the two.
Preferably, in above-mentioned horizontal piston, a plurality of described drainback passages around be arranged at described horizontal piston cylindrical upper side circumferentially.
Preferably, in above-mentioned horizontal piston, described drainback passage is three, and is evenly distributed on described horizontal outside piston upper side.
Preferably, in above-mentioned horizontal piston, the oil outlet end of described drainback passage is communicated with one end of described oil duct in piston near the bottom of described horizontal piston compared with it.
, in its cylinder sleeve, being provided with horizontal piston, described horizontal piston is the as above horizontal piston described in any one.
The horizontal piston that the utility model provides, its inside is provided with oil duct in piston, is provided with the drainback passage that is communicated with oil duct in piston on the cylindrical upper side of horizontal piston.When horizontal piston is worked in cylinder sleeve, lubricant oil flows in oil duct in piston, when horizontal piston movement, lubricant oil is entered on the cylindrical upper side of horizontal piston by drainback passage, and form lubricant film between the cylindrical upper side of horizontal piston and cylinder sleeve, thereby make to form preferably and lubricate between horizontal piston and cylinder sleeve, efficiently solve surperficial generation of horizontal outside piston upper side and cylinder sleeve and pull, guaranteed the trouble free service of internal-combustion engine.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The sectional view of the horizontal piston that Fig. 1 provides for the utility model;
The plan view of the horizontal piston that Fig. 2 provides for the utility model.
Embodiment
The utility model discloses a kind of horizontal piston, solved horizontal outside piston upper side lubricant oil and formed difficult problem; The utility model also provides a kind of horizontal internal combustion engine.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is carried out to clear, complete description, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Based on embodiment of the present utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
The sectional view of the horizontal piston that as depicted in figs. 1 and 2, Fig. 1 provides for the utility model; The plan view of the horizontal piston that Fig. 2 provides for the utility model.
A piston, its inside is provided with oil duct in piston 1, is provided with the drainback passage 2 that is communicated with oil duct in piston 1 on the cylindrical upper side 3 of horizontal piston.When horizontal piston is worked in cylinder sleeve, lubricant oil is interior mobile at oil duct in piston 1, when horizontal piston movement, lubricant oil is entered on the cylindrical upper side 3 of horizontal piston by drainback passage 2, and form lubricant film between the cylindrical upper side 3 of horizontal piston and cylinder sleeve, thereby make to form preferably and lubricate between horizontal piston and cylinder sleeve, efficiently solve surperficial generation of horizontal outside piston upper side and cylinder sleeve and pull, guaranteed the trouble free service of internal-combustion engine.
In the utility model one specific embodiment, between the cylindrical upper side 3 of horizontal piston and oil duct in piston 1, be provided with a plurality of drainback passages 2 that are communicated with the two.The cylindrical upper side 3 of horizontal piston is all difficult for receiving the lubricated of lubricant oil when normal operation, arrange after drainback passage 2, for guaranteeing all lubricated glossy sliding into of whole cylindrical upper side 3, need to guarantee can be coated on whole cylindrical upper side 3 after lubricant oil is by the interior outflow of drainback passage 2, the cylindrical upper side 3 of horizontal piston radially has the peak of an arc at it, for guaranteeing that the both sides of horizontal piston extreme higher position are all subject to the lubricated of lubricant oil, need reasonably arrange the position of drainback passage 2.Particularly, when drainback passage 2 is one, be arranged at the extreme higher position of cylindrical upper side, the lubricant oil flowing out is flow between whole cylindrical upper side 3 and cylinder sleeve.
In the utility model one specific embodiment, a plurality of drainback passages 2 around be arranged at horizontal piston cylindrical upper side 3 circumferentially.Drainback passage 2 arranges a plurality of, by putting in circumferential pressed on ring winding, while making lubricant oil on the cylindrical upper side 3 that is flow to horizontal piston by drainback passage 2, can lubricant oil be distributed on the cylindrical upper side 3 of whole horizontal piston by a plurality of drainback passages 2 that week upwards arranges, thereby guarantee the lubrication effect of horizontal outside piston upper side.
Particularly, drainback passage 2 is three, and is evenly distributed on horizontal outside piston upper side 3.Drainback passage 2 is set to three, and is uniformly distributed, and in the present embodiment, three 2 one of drainback passages are arranged on extreme higher position on horizontal outside piston, and all the other two are arranged on this both sides, extreme higher position.
