GUIDE DEVICE FOR DRIVE ROD FOR USE WITH DRIVES OF HYDRAULIC VALVE Russian patent published in 2016 - IPC F16K31/165 

FIELD: machine building.

SUBSTANCE: guide device for a drive rod for the use with the drives of a hydraulic valve is suggested, it has a membrane located in the casing. The suggested device contains a base, located inside the casing and surrounded by a displacing element, having the hole, ensuring the possibility of inclination of the drive rod of the hydraulic valve in the base, and so the possibility of rotation of the drive lever of the hydraulic valve, and the top end of the base specifying area for the reception of the guide located near the base hole. The guide by a disconnecting method is connected with the base in the area for the reception of the guide, and has a support surface interacting with the possibility of sliding with the drive rod and limiting the side movement of the membrane assembly relatively to the longitudinal axis of the hole, and such preventing the interaction of the membrane assembly and internal surface of the drive casing during the drive rod movement between the first position and the second position. The top end of the base has the first holes, and the guide has the second holes, that are aligned with the appropriate holes in the top end of the base, to receive the fasteners connecting the guide and the base.

EFFECT: improved design.
