2 WAY CYLINDER AND BRAKE SYSTEM USING THE SAME

摘要

PURPOSE: A 2 way cylinder and a brake system adopting the same are provided to secure the complete braking power through the rest circuit when a circuit is broken down by connecting vehicle braking pedals to a brake of a transmission through a 2 way oil-hydraulic circuit. CONSTITUTION: A 2 way cylinder(100) comprises an outer housing(30) and an inner housing(32). The outer housing surrounds the cylinder so as to be movable and presses a part of the cylinder. In the outer housing, an outer flow path(38) is formed. The inner housing is expanded to the inside of the cylinder and presses the other part of the cylinder. In the inner housing, an inner side flow path(36) is formed. Cross sections of the cylinder to which the fluid pressure is applied are the same. An external chamber(34) and an inner chamber(33) of the cylinder are formed between the outer flow path and inner side flow path.
