Abstract
A reciprocating member and a retainer cooperate to limit rotation of the reciprocating member in a bore. Grooves in the reciprocating member cooperate with corresponding portions of a retainer to guide the reciprocating member and limit rotation of the member in the bore due to the compressive engagement of a portion of the retainer by the bore.
Claims5
An anti-rotating guide for a reciprocating member comprising:
- a spool member reciprocally mounted within a bore, the spool having a first groove radially annularly formed therein adjacent the bore and an elongated second groove including a first end communicating with the first groove and extending therefrom substantially axially along the spool adjacent the bore and terminating within the bore at a closed second end;
- and
- a retainer mounted on the spool, the retainer having an annular radially flexible first portion of the retainer in the first groove being of a construction sufficient to be compressed by the bore and an elongated second portion of the retainer extending along the second groove and terminating therein.
