#Pushrod and slack adjuster serial#
Descriptionġ19~Z~ O This is a division of Canadian Patent Application Serial No. Lost motion is provided to prevent rotation of the nut on the rod during normal push rod clearance, and rotation of the nut on the push rod occurs when excessive push rod clearance occurs. A nut is threaded onto the rod and engaged by the driven cam member to transmit axial force to the push rod and relative extension of the push rod from the cam members is accomplished by a one way spring brake acting on the nut and a disc clutch drive between the driving cam and nut. The push rod is held against rotation intern-ally of the housing by a flange whose periphery is frictionally engaged by the return spring. A helical return spring is positioned between the driven cam and the inner wall of the housing to bias the cam members together. The driving and driven helical cam members are located in a housing with the actuating shaft extending out of one end thereof and a threaded push rod extending out of the other end of the housing. An axially extending rotating actuating shaft turns a helical, driving cam member that in turn axially displaces a non-rotating driven cam member.
