Abstract
A master brake cylinder includes a unique mounting arrangement for securing thereof to a firewall of a vehicle and a particular porting arrangement. A cylinder sleeve includes a series of ports that cooperate with movement of the piston allowing for by-passing of the piston at one end position and then movement of the piston past the ports for brake actuation. Additionally a two stage pressure intensifier is provided that is in-line between a master brake cylinder and brake pistons. The intensifier also includes a by-pass position at one end of the movable piston having a differential area between a forward and a rear face of the piston.
Claims6
A master brake cylinder comprising:
- a spring biased piston movable in a cylinder to pressurize a brake fluid in one direction of movement and to remove brake fluid pressure when moved in a direction opposite to said one direction;
- said piston including a push rod fixed to one side of said piston and extending out of said cylinder and through a bushing closing one end of said cylinder;
- said bushing including an extension with an exposed threaded exterior surface that receives and cooperates with a ball member threadingly secured thereto;
- said ball member having a pivot pin extending outwardly from an outer surface of said ball member;
- and
- a mounting bracket located on said push rod between said threaded bushing and said ball member;
- said mounting bracket having a ball socket opening towards said ball member and sized to receive and pivotally retain said ball member and a receiving slot sized to receive said pivot pin on said ball member;
- said mounting bracket further including a mounting arrangement for fixedly securing said mounting bracket to a firewall of a vehicle to retain said ball member between said mounting bracket and the firewall of the vehicle;
- the firewall of the vehicle being provided with a port allowing said push rod to extend through said firewall.
