GUIDE ELEMENT FOR VALVE ACTUATOR Russian patent published in 2017 - IPC F16K7/12 F16K27/08 F16K31/126 

FIELD: mechanism.

SUBSTANCE: valve actuator unit comprises housing, containing membrane plate and membrane, placed inside housing. Rod attachment projection passes downwards from membrane plate lower surface, wherein rod attachment projection is connected to actuator rod, passing in lengthwise axis direction. Guide element includes upper wall and central opening, through which rod attachment projection is passing, and due to spring action upper wall is pressed to membrane plate lower surface. Guide element additionally includes side wall, which passes from upper wall in downward direction, wherein side wall outer surface interacts with spring casing internal surface in order to limit membrane and actuator rod displacement in direction, perpendicular to longitudinal axis.

EFFECT: membrane plate rod attachment projection, besides, passes through guide element upper wall central hole to limit guide element displacement relative to membrane plate in transverse direction.
