SU14408A1 - Piston for hydraulic cylinders - Google Patents

Description

In order to avoid the use of leather cuffs in spacers for hydraulic cylinders, a piston is proposed, consisting of several split cups inserted one into another, which can spring back and be torn from the inside by spring. a ring that presses the cylindrical walls of the piston against the walls of the hydra, cylinder;

In FIG. 1 shows a longitudinal section of the piston; FIG. 2 - view of its bottom.

In the hollow piston 1, having the form of a glass, are inserted glasses 2, 3, 4, 5, nested one inside the other. The piston, as well as the glasses inserted into it, is provided with through slots 9 in the direction of the producing cylindrical. surfaces and assembled. so that the cuts in each glass or piston are overlapped by solid portions of adjacent staples. Into the inner cup a spring-loaded split ring 6 is inserted, held by the washer 7. All the glasses are equal and the washer 7,

fastened with piston 1 screw stud 8 ..

During the operation of the piston, the spring ring 6 bursts all the cups and the piston itself, pressing them against each other and against the walls of the cylinder, as a result of which the inventor believes that it is difficult for the fluid to leak between the piston and the walls of the hydraulic cylinder.

Subject patent.
