Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
79 words
A vacuum suspended brake booster (11) comprising a housing divided into two chambers by a movable wall (23), valve means (29) responsive to a booster input load for controlling a differential pressure across said wall (23) to provide a proportionately increased output load, and reaction means (13) for transmitting reaction loads from said output to said input characterised thereby that said reaction means (13) comprise at least one tie bar accommodated in a re-entrant portion of the booster periphery.
Claim 2
Dependent Claim
79 words
A vacuum suspended brake booster (11) comprising a housing divided into two chambers by a movable wall (23), valve means (29) responsive to a booster input load for controlling a differential pressure across said wall (23) to provide a proportionately increased output load, and reaction means (13) for transmitting reaction loads from said output to said input characterised thereby that said reaction means (13) comprise at least one tie bar accommodated in a re-entrant portion of the booster periphery.
Claim 3
Dependent Claim
36 words
A booster according to Claim 1, characterised thereby that said booster (11) is symmetrically waisted about its operating axis so as to provide a pair of opposite re-entrant portions each to accommodate one tie bar (13).
Claim 4
Dependent Claim
25 words
A booster according to Claim 2, characterised thereby that each tie bar (13) is located in a bore in the wall of the booster housing.
