Abstract

1340048 Fluid pressure brake boosters GIRLING Ltd 19 April 1971 [11 April 1970] 17296/70 Heading F2F A servo booster for vehicle brake systems comprising a housing 10 divided by a flexible diaphragm 16 into two axially separate fluid chambers 12, 14, the former being connected permanently to vacuum and the latter being selectably connectible by a valve assembly 18 either to chamber 12 or to atmosphere includes a valve seat member 30 axially displaceable by means of a push rod assembly rigidly located relative to the member 30 by a self locking means including a tubular nut 46 having a frusto-conical portion (58) which is deformed radially inwardly by contact with a bore 40. The nut is of a material such as polypropylene.
