Patent ID: 6993907

Claim:
A hydraulic brake pressure intensifying apparatus ( 10 ) comprising: a fluid cylinder ( 40 ) axially extending between an inlet end ( 44 ) and an outlet end ( 46 ) and defining a cylindrical chamber ( 42 ) extending therethrough wherein said fluid cylinder ( 40 ) includes a first end wall ( 116 ) for sealing said chamber ( 42 ) proximal to said inlet end ( 44 ) and a second end wall ( 118 ) for sealing said chamber ( 42 ) proximal to said outlet end ( 46 ); a piston assembly ( 52 ) slidably disposed in said cylindrical chamber ( 42 ) for regulating fluid flow between said inlet end ( 44 ) and said outlet end ( 46 ) and including a first piston ( 54 ) having a first forward end ( 54 a ) adjacent said inlet end ( 44 ) and a first outer annular wall ( 100 ) extending from said first forward end ( 54 a ); and said apparatus ( 10 ) characterized by said first end wall ( 116 ) defining a plurality of apertures ( 110 ) adjacent to said first outer annular wall ( 100 ) for allowing the fluid to flow around said first outer annular wall ( 100 ) and into said piston assembly ( 52 ).
