Oil-gas Separation case (1), baffle arrangement (12), steam outlet pipe (13) become one die cast.
Oil-gas Separation case (1) is processed seal groove (11).
Baffle arrangement (12), gathering room (23) are welded as a whole.
Return tube (24) to stretch in gathering room (23) and is welded and fixed, and oil gas entrance (211), guide plate (22) are welded on gathering room baffle plate (21).
The invention has the beneficial effects as follows:
1, labyrinth and the integrated cast inblock of case, compact structure, reduces Assembly part quantity, and reduces complete machine cost;
2, by specially designed gas and oil separating plant suction port direction, the machine oil content in oil gas is reduced; The labyrinth deflection plate knuckle obtained afterwards as calculated, effectively can improve the separation effect of gas and oil separating plant;
3, not need in this device outside external oil collecting gas separating device again, reduce machine part quantity, simplify arrangement.

Reference character: Oil-gas Separation case (1), seal groove (11), baffle arrangement (12),
Steam outlet pipe (13), Oil-gas Separation gathering room (2), gathering room baffle plate (21), oil gas entrance (211), main spill port (212), auxiliary little spill port (213), guide plate (22), gathering room (23), return tube (24), Shock-proof bolt assembly (3), seal ring (4), construction bolt (5).
Embodiment
Most preferred embodiment of the present invention is such, embodiment 1, with reference to accompanying drawing, and gas and oil separating plant structure of the present invention, become one Oil-gas Separation case (1) and baffle arrangement (12), steam outlet pipe (13) die casting, Oil-gas Separation case (1) processed seal groove (11); Gathering room baffle plate (21) and gathering room (23) weld together, and return tube (24) to stretch in gathering room (23) and is welded and fixed, and oil gas entrance guide plate (22) is welded on auxiliary oil gas on gathering room baffle plate and enters guiding adjustment; Oil-gas Separation gathering room (2) construction bolt (5) is installed on Oil-gas Separation case (1); Seal groove (11) on Oil-gas Separation gathering room (2) installs seal ring (4), and sealing ring material adopts AEM material, and heat resistance is higher, good sealing effect; By Shock-proof bolt assembly (3), Oil-gas Separation case (1) is secured on cylinder head cover, forms gas and oil separating plant.
