Abstract
The utility model discloses a piston top, which is provided with three gas ring grooves, a lateral cavity, an inner cavity, an oil return cavity and a combustion chamber. The piston top with the structure is made of existing materials with high strength and low temperature expansion, can replace a combined piston, accordingly, is lower in cost, and can work continuously under severe working conditions such as heavy oil burning, high detonation pressure and the like.
Description
Technical field
The utility model relates to a kind of piston head.
Background technique
In the existing technology, the compression on the piston head is too concentrated, excesssive gap, and cause piston top precision is not enough.
Summary of the invention
The purpose of the utility model provides a kind of piston head.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of piston head, said piston head are provided with three compressions, side chamber, inner chamber, oil back chamber and firing chamber.
Said inner chamber is the U die cavity.
A kind of piston head of the utility model, the material that present high tenacity, low temperature expand has been used for this structural type piston, makes cost more cheap, and can be under abominable operating mode such as burning heavy oil, high detonation pressure, continual work.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of a kind of piston head of the utility model.
Embodiment
As shown in Figure 1, the utility model piston head, this piston head is made up of compression 1, side chamber 2, inner chamber 3, oil back chamber 4 and firing chamber 5 parts, and compression 1 has three, and inner chamber is the U die cavity, and inner chamber 3 diameters are 140mm, its intracavity diameter Φ is 180mm.
Claims (2)
1. piston head, it is characterized in that: said piston head is provided with three compressions, side chamber, inner chamber, oil back chamber and firing chamber.
2. a kind of piston head according to claim 1 is characterized in that: said inner chamber is the U die cavity.
