Abstract
The antirotational, mechanical lash control mechanism for two reciprocating bodies having opposing cylindrical surfaces uses a radial U-shaped groove in the outer surface of the outer housing; a radial cut in the leg of said U-shaped groove, that extends from the groove into said bore; a U-shaped clip adapted to fit the U-shaped groove, the U-shaped clip having a ledge on a leg of U-shaped clip, where the ledge extends through said cut and into said bore; and a first stop on the outer surface of the inner housing, such that the first stop abuts said ledge to control mechanical lash between the outer housing and the inner housing. To prevent rotation, the ledge has a flat surface that mates to a flat surface on the inner housing.

A mechanical lash control mechanism for two reciprocating bodies having opposing cylindrical surfaces, comprising:
- (a) an elongated outer housing having an outer surface and a cylindrical bore therein;
- (b) a cylindrical inner housing positioned in said bore for reciprocal movement therein, said inner housing having an outer cylindrical surface;
- (c) a radial U-shaped groove in the outer surface of the outer housing, said U-shaped groove having a first and second leg;
- (d) a first radial cut in the first leg of said U-shaped groove, said cut extending from said groove into said bore;
- (e) a U-shaped clip adapted to fit said U-shaped groove, said U-shaped clip having a first and second leg;
- (f) a first ledge on said first leg of said U-shaped clip, said ledge extending through said first cut and into said bore;
- and
- (g) a first stop on said outer surface of said inner housing, such that said first stop abuts said first ledge to control mechanical lash between the outer housing and the inner housing.
An antirotational mechanism for reciprocating bodies having opposing cylindrical surfaces comprising:
- (a) an elongated outer housing having an outer surface and a cylindrical bore therein;
- (b) a cylindrical inner housing positioned in said bore for reciprocal movement therein, said inner housing having an outer cylindrical surface;
- (c) a radial U-shaped groove in the outer surface of the outer housing, said U-shaped groove having a first and second leg;
- (d) a first radial cut in the first leg of said U-shaped groove, said cut extending from said groove into said bore;
- (e) a U-shaped clip adapted to fit said U-shaped groove, said U-shaped clip having a first and second leg;
- (f) a first ledge on said first leg of said U-shaped clip, said ledge extending through said first cut and into said bore, said first ledge having a flat axial surface;
- and
- (g) a first axial indentation on said outer cylindrical surface of said inner housing, said first indentation having a flat axial surface that matches said flat axial surface of said first ledge to prevent rotation of the inner housing in the bore.
An antirotational, mechanical lash controlling mechanism for two reciprocating bodies having opposing cylindrical surfaces comprising:
- (a) an elongated outer housing having an outer surface and a cylindrical bore therein;
- (b) a cylindrical inner housing positioned in said bore for reciprocal movement therein, said inner housing having an outer cylindrical surface;
- (c) a radial U-shaped groove in the outer surface of the outer housing, said U-shaped groove having a first and second leg;
- (d) a first radial cut in the first leg of said U-shaped groove, said cut extending from said groove into said bore;
- (e) a U-shaped clip adapted to fit said U-shaped groove, said U-shaped clip having a first and second leg;
- (f) a first ledge on said first leg of said U-shaped clip, said ledge extending through said first cut and into said bore;
- (g) a first axial indentation on said outer cylindrical surface of said inner housing, said first indentation having a flat axial surface that matches said flat axial surface of said first ledge to prevent rotation of the inner housing in the bore;
- and
- (h) a first stop positioned at one axial end of said first indentation to control mechanical lash between the outer and inner housing.
