Description

In the present invention, a telescopic piping system for cooling pistons in internal combustion engines is provided to prevent the ingress of oil into the water circulating through the pistons, the water seal on the end of the movable pipe sliding inside the stationary stuffing box and the guide bush oiled

In FIG. 1. Depicts a front view of the proposed device with cuts of the covers; FIG. 2 is a top view of the proposed device; FIG. 3 is a section along line AB in FIG. .

A movable elastic pipe 1 with double walls is attached to the piston bracket, sliding in the guide sleeve 14, over which is placed the gland 27, which is pushed by the pressure nut 12, screwed onto the existing case 18, which, due to the large diameter of the movable pipe 1, is bored to the desired size. Babbitt rings 19 are placed in the housing 10, removing the oil from the outer surface of the pipe 1 and discharging it through the opening 28. Inside the moving pipe 1 there is a stationary pipe 2 attached by means of a bracket 17 to the engine cylinders; pipe 2 is taken from existing water cooling

piston and only shortened. At the upper end of the movable pipe 1, a housing 3 is placed in which there is a water seal 25 pushed by a nut 8 displaced in a body 5 screwed on the housing 3 and secured with a screw 33. Water seeping through the omentum is discharged by tube 7 and drained into collecting tank through pipe 26. So that the water splashing at the outlet of pipe 7 and precipitating on the outer pipe 1 could not penetrate downwards into the oil space, an oil seal 36 is placed in the upper part of the body 10. The movable parts of the pipes are covered with a casing 24, which there are inspection holes for ablyudeni the work; pipes and water seal. A water cap 23 is attached to the cylinder tides. divided by a partition into two parts, in which the open ends of the pipes 21 are placed, each of which is connected to the pipe 2 by the elbow 16. The right (according to the drawing) part of the cap 23 through which water is supplied to the piston has air space to compensate for hydraulic shocks. Water flows from the pump first into the cap through the opening 30 and then through pipes 21,26 and telescopic pipes rises into the piston. Drainage of water from: piston produced by another system.

The telescopic tubes, through the left tubes 21, 26, the water being brought into the common pipeline from the left cap through the opening 29. On the right handle, to establish a certain level of water, there is a cj "ioTpoBoe glass 31.

The subject of the patent.

A device for cooling pistons in internal combustion engines, consisting of elastic telescopic pipes with double walls and a gland seal, characterized in that each of the pipes 1 connected to the engine piston, sliding inside the stationary oil-lubricated gland 27, ends with a second gland 25, inside of which the pipe 2 slides without lubrication with oil, fixed relative to the engine block.
