Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
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.
Claim 2
Dependent Claim
114 words
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.
Claim 3
Dependent Claim
17 words
The anti-rotating guide of claim 1 wherein: the second groove is normally disposed with the first groove.
Claim 4
Dependent Claim
20 words
The anti-rotating guide of claim 2 wherein: the second portion of the retainer is integratedly formed with the first portion.
Claim 5
Dependent Claim
20 words
The anti-rotating guide of claim 3 wherein: the second portion of the retainer is normally disposed with the first portion.
Claim 6
Dependent Claim
20 words
