    Invention m. used in vehicle brake systems. The purpose of the invention is to increase the strength of a tandem master cylinder. In two molded parts x 1, 2 cylinders made of plastic material. pistons with seals are mounted, forming chambers 17. 21 pressures. Pistons are installed in the chambers 17. 21 with the possibility of sliding. Each part 1. 2 is surrounded by a hollow cylindrical body 7, 8. attached to the corresponding part 1, 2 outside the stroke of the seals in this part. The free ends of the housings 7. 8 are interconnected and mounted opposite to each other, a rigid element with flat opposite oriented faces is placed between them, the ends are tightly sealed, the Element is equipped with means for fixing parts 1, 2 in axial and radial directions. Cases 7. 8 are equipped with a reservoir for the working fluid and a mounting flange 10. The pistons are made in the form of nodes that interact with each other by transferring forces. The annular space between parts 1, 2 and shells 7. 8 communicates with the reservoir and the chambers 17, 21. 10 Cp. f-ly, 2 ill. (L with

    Claims (11)
    [1]
    Claim
    1. A tandem master cylinder, comprising at least two separately formed cylinder parts made of plastic material, each of which includes a pressure chamber, sealed pistons mounted in sliding chambers, characterized in that. in order to increase strength, each of the cylinder parts is surrounded at least in part by a hollow cylindrical body attached to the corresponding cylinder part outside the piston seal stroke in this part, the free ends of the bodies being interconnected.
    [2]
    2. The cylinder according to claim 1, characterized in that the hollow bodies with free ends are mounted towards each other, between them there is a rigid element with flat oppositely oriented faces relative to which the free ends of the hollow bodies are sealed.
    [3]
    3. The cylinder according to claim 2, characterized in that. that the rigid element is provided with means for fixing the cylinder parts in the axial and radial directions.
    [4]
    4. The cylinder according to claims 1 to 3, characterized in that. that the parts of the cylinder parts forming the pressure chambers are provided with reinforcing elements surrounding them.
    [5]
    5. The cylinder according to claims 1 to 4, characterized in that the hollow bodies are equipped with a reservoir for the working fluid and a mounting flange for attaching to the support, respectively,
    [6]
    6. The cylinder according to claims 1-5, characterized in that. that the pistons are made in the form of nodes interacting with each other by transmitting force.
    [7]
    7. The cylinder according to claims 1-6, characterized in that. that the hollow bodies are connected by free ends directly. and the mounting flange is mounted on the front in the direction of movement of the pistons of the cylinder.
    [8]
    8. The cylinder according to claim 7, characterized in that the hollow bodies are connected to each other by welding.
    [9]
    9. The cylinder according to claim 7, characterized in that. that the hollow bodies are connected by adhesion.
    [10]
    10. The cylinder according to claims 1 to 9, starting with the fact that the outlet openings of the respective pressure chambers are made at the junction of the hollow bodies.
    [11]
    11. The cylinder according to claims 1 to 10, with the exception of that. that the annular space between the cylinder parts and the hollow bodies is in communication with the working fluid reservoir and pressure chambers.
