Abstract: A shower dispenser adapted to be connected to a water pipe at one end and having a shower head connected to the opposite end includes a through passage for water from the water pipe to the shower head which is surrounded by an annular reservoir for receiving liquid soap or the like. A transverse passage intersects the through passage and a spool valve having a measuring chamber therein is slidably mounted in the transverse passage. The chamber is provided with ports which will be aligned with a dispensing port communicating with the reservoir when the spool valve is in a first position and which will be disposed in the through passage when the spool valve is in a second position. The spool valve has a reduced diameter portion which is completely disposed within the through passage in the first position of the spool valve and partially within the through passage when the spool valve is in the second position.
