Abstract (en)
The hydrant has a valve closure part pressed against a seat by a sleeve tube operated by a spindle. The part is a closure ball (11) and is pressed against its seat by a pressure shoe (10) connected to the tube. When the hydrant is open, the ball moves freely between an upper open position and a lower closing position. The shoe is connected to the tube via a retainer bolt (8), and the closure ball guide is formed by evenly positioned cage bars (20). The upper bar ends are connected to a slide sleeve (22), which engages around the bolt with slide play.
