Embodiment
Describe the present invention with reference to the accompanying drawings below, it is a kind of preferred embodiment in the numerous embodiments of the present invention.
Present embodiment relates to a kind of lengthened piston of optical engine, and it is mainly by piston head window portion 1,2, two groups of compression piston rings 3 of piston elongated portion, two inconel C type rings 4, bolt 5, transparent window 6, grommet 7,9, oil control ring 8, piston pin hole 10, scraper ring 11 waits part to form.The piston head window portion 1 of this lengthened piston is connected by bolt 5 with piston elongated portion 2, and simple in structure, transparent window is quick detachable.Two groups of grommets are arranged on this lengthened piston simultaneously, guarantee that lengthened piston is along cylinder sleeve 12 axis vertical motions.
1. lengthened piston 13 is made up of piston head window portion 1 and piston elongated portion 2 two-part.The top has the circular hole that transparent window 6 is installed, and piston elongated portion 2 both sides have the side window that reflector 15 is installed.
2. all to adopt be aluminum alloy material for the top window part 1 of piston and piston elongated portion 2, reduces the solid piston quality.
3. piston head window portion 1 is to connect together by bolt 5 with piston elongated portion 2, with two inconel C shape rings 4 top transparent window 6 is clamped its sealing of assurance, make piston head window portion 1 and transparent window be easy to assembling and dismounting, thereby be convenient to change and cleaning transparent window 6.
4. one group of scraper ring 8 is arranged on the piston elongated portion 2, and scraper ring 8 can reduce machine oil on the casing wall, and the oil control ring 11 of downside strikes off remaining machine oil once more and makes back crankcase.
5. be furnished with two groups of grommets 7,9 on piston elongated portion 2, grommet 7,9 guarantees that lengthened piston is along cylinder sleeve 12 axis vertical motions.
6. in optical engine, transparent cylinder sleeve 12 can not bear the wearing and tearing of steel piston ring.In the present invention, compression piston ring 3 adopts the graphite of special processing to make, and has sealing, lubricated, high temperature resistant effect, and thermal conductivity is preferably arranged.
