Claims

[Claims for Utility Model Registration] A symmetrical piston 2 inserted into a cylinder body 1
Flanges 4a, 4b are provided on the small diameter portions 3a, 3b at both ends of the piston 2, and at least three legs 7a, 7b of the synthetic resin valves 5a, 5b arranged at both ends of the piston 2 are connected via coil springs 5a, 5b. Tip bent portion 8a, gb
is a medium diameter portion 9a of the piston 2, which is configured to be slidable along the small diameter portions 3a, 3b and to be hooked on the flanges 4a, 4b. The sleeve piston lea is slidably fitted between 9b and the cylinder body 1, and 10b is the cylinder body 1.
Set bolt 11a screwed into. 11b, and the sleeve pistons 10a and 10b are always moved away from the piston 2 by compression return springs 13a and 13b arranged between the side surface of the large diameter portion 12 of the piston 2 and the end surfaces of the sleeve pistons lea and 10b. passage 2 from the two hydraulic chambers 15a, 15b of the tandem master cylinder.
0a. 20b are guided through two annular groove-shaped passages 22a and 22b provided on the outer periphery of the piston 2 to the left and right front wheel cylinders 16 and 17, respectively, and passages 26a and 26b provided inside the piston 2 and valves @a and fib. A proportional pressure reducing valve for a two-system brake system, characterized in that it is led to a wheel cylinder 18, 19 of the opposite rear wheel through an opening/closing passage with sleeve screws 710a and 10b.
