Separate 3-cylinder system of brake fluid for automobile safety

A pressing cylinder adapted to be connected to the master brake cylinder of an automobile braking system and for independently transmitting fluid pressure to the front wheel cylinders and right and left wheel cylinders in response to manual operation of an automobile brake pedal to effect braking action of said automobile, said pressing cylinder comprising in combination:

• body means defining a front cylinder and right and left rear cylinders, said front cylinder having a larger bore than each of said right and left rear cylinders, said body means including piston means slidably and reciprocably engageable in each of said front cylinder and right and left rear cylinders, said piston means including sealing means sealingly engageable with said front cylinder and left and right rear cylinder defining means for separating each of said front cylinder and said right and left rear cylinders into a fluid receiving chamber for receiving fluid from said master cylinder and a fluid discharge chamber for discharging fluid to said front wheel cylinders and said right and left rear wheel cylinders, respectively, in response to manual operation of said brake pedal;
• first means covering said fluid receiving chamber including means defining a fluid receiving passageway, one end thereof for connection to said master cylinder, and the other end thereof for concurrently distributing brake fluid from said master cylinder to said front cylinder and said right and left rear cylinders;
• and
• second means covering said fluid discharge chamber including means defining fluid discharge passageways in operative communication with said front cylinder and said right and left rear cylinders for allowing brake fluid to pass therethrough in response to manual operation of said brake pedal and for connecting said pressing cylinder to said front wheel cylinders and right and left rear wheel cylinders respectively.
