Abstract
The utility model relates to an energy saving single air ring piston belonging to the class of machinery, which is used for internal-combustion engines and air pumps. The utility model is composed of a piston, an air ring, a sliding block, etc. The piston has only one air ring groove and uses only a C type air ring. A blind hole is arranged at the air ring groove, and the sliding block and a spring is arranged in the hole. The notch of the air ring is fixed in the sliding block, and the spring pushes the sliding block to seal the notch of the air ring. As a result, the seal performance of the air ring is enhanced. The utility model uses fewer air rings than multiple air ring pistons, so that the friction between the air ring and the cylinder sleeve is reduced, and the abrasion of the cylinder sleeve is reduced at the same time. The utility model has the advantages of simple structure, easy fabrication, good energy saving effect, and longer service life of the cylinder sleeve.
Description
It belongs to mechanical.Be used for internal-combustion engine and air pump.
The piston that is used for internal-combustion engine and air pump at present mainly contains:
Many compression rings piston: reach sealing for making piston and cylinder liner, use many C type compression rings breach that staggers, be installed in the compression of piston, but its sealing not exclusively, cylinder inner high voltage gas can pass through the breach of compression ring and the gap of piston and cylinder sleeve, and the waste part energy.The compression ring number of elements is many, and is bigger with the frictional force of cylinder sleeve, not only loss part energy, and also bigger to the wearing and tearing of cylinder sleeve.
The purpose of this utility model provides a kind of energy-saving piston, and it reduces to one with the compression ring of piston, reduces the friction of compression ring and cylinder liner.Utilize the breach of slide block sealing compression ring, improve the sealability of compression ring.
The purpose of this utility model is achieved in that it is made up of piston, compression ring, slide block, spring, oil ring etc.Piston has only compression one, only uses a C type compression ring, and the compression place of piston is shaped on a blind hole, and the hole can be a circular hole, also can be that two is the long shape hole of semicircle.Slide block and spring are housed in the hole, and slide block and blind hole adopt accurate activity to cooperate.Sliding outer end of determining is circular arc, and one section compression is wherein arranged, and the breach of compression ring is fixed therein.Slide block is under the promotion of spring, and its outer end contacts closely with cylinder wall, closes the gap between compression ring breach and the cylinder liner.Slide block adopts wear-resisting metallic material or pottery to make, and its thermal expansion coefficient is not more than piston.Oil ring is contained in the oil ring groove.
The invention has the advantages that simple in structurely, easily manufactured, reduced the quantity that piston uses compression ring, thereby reduced the frictional force of compression ring and cylinder liner and, and improved the sealability of compression ring the wearing and tearing of cylinder liner.Energy-saving effect is remarkable, can prolong the working life of cylinder liner again.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is A-A sectional view of Fig. 1;
Fig. 3 is B-B sectional view of Fig. 1;
Fig. 4 is 2: 1 big plan views of side of slide block.
Among the figure 1, piston 2, compression ring 3, slidingly determine 4, spring 5, oil ring.
In the embodiment shown in the figures, piston (1) only is shaped on compression one, only uses a C type compression ring (2), and the compression place is shaped on a circular blind hole.Slide block (3) is a cylindrical body, and the outer end is circular arc, wherein is shaped on one section compression, and bottom land has a pore, connects the two ends of slide block (3), and trough rim has a cylindrical fixing pin, and to projecting inward half cylinder of groove, it highly is 1/2 of a groove depth.The inner circular hole of slide block (3) cooperates with spring (4).The surface of slide block (3) and blind hole cooperates through being finish-machined to accurate activity.Compression ring (2) breach both sides respectively eliminate 1/4 cylindrical body, make compression ring (2) form semi-cylindrical canyon when two ends close up, and its length is 3/5 of compression ring (2) thickness, and the degree of depth is 1/2 of compression ring (a 2) height, cooperate with fixing pin in the slide block (3).The fixing pin of the notch alignment slide block (3) of compression ring (2) compression of packing into, fixing pin is fixed on the breach of compression ring (2) in the compression of slide block (3).Pore in the slide block (3) can its two ends of balance air pressure, at the bottom of avoiding when the high pressure of its outer end pushing loose piece (3) to blind hole, and the influence sealing.Oil ring (5) is contained in the oil ring groove.
Claims (2)
1, a kind of single compression ring energy-saving piston is made up of piston, compression ring, slide block, spring, oil ring etc., and it is characterized in that: piston has only compression one, only uses a C type compression ring, and the compression place is shaped on a blind hole, and slide block and spring are housed in the hole.
2, single compression ring energy-saving piston according to claim 1, it is characterized in that: the outer end of slide block is circular arc, wherein is shaped on one section compression, and bottom land has a pore, and trough rim has a cylindrical fixing pin.
