The interceptingvalve is placed on the right-hand side of the en-gine within the saddle of the low-jDressure cyl-inder and in the passages HE, leading from thereceiver to the low-pressure cylinder, as shownin Fig. 174; it also has two connecting ports AA,leading into the main exhaust to the stack. Bythe movement of this valve, steam from the high-pressure cylinder, coming through the receiver,can be thrown out to the atmosphere insteadof being allowed to pass to the low-pressure cyl- 2^i^
