[Class 135.] An ant,iwater-hammer device for pipe lines carrying liquid under pressure comprises an air chamber 1 in the lower part of which is located a convergent nozzle 2 on the end of the inlet pipe 3 and a divergent nozzle 4 on the end of the outlet pipe 4<1>. The level of water in the chamber is adjusted by draw-off taps 7 and compressed air may be admitted through a pipe 5 to replenish the space 1<1>. In the form shown in Fig. 2 the outlet pipe 4<1> is branched off the inlet pipe 3 and the divergent nozzle is connected by a pipe 8 to the top of the chamber. In a modification of this form the pipe 8 is arranged concentrically within the chamber. |
