PURPOSE:To improve the water flow rate characteristics and also to reduce noise by providing an inner core and an O-ring for maintaining a constant flow rate in parallel with an inner core and an O-ring for a variable water flow rate which enable the water flow rate to be adjusted from the outside of the apparatus. CONSTITUTION:As a water feed connecting pipe 13 is disposed in the center relative to a water inlet body 14, after entering the pipe 13, the water is divided into two parts, one passing through a water flow control section for maintaining a constant water flow rate which is formed by attaching a water governor housing 18, an O-ring and an inner core 20 for a constant water flow rate to a water flow rate adjusting body 15, and the other passing through a water flow rate control section for a variable water flow rate which comprises a water governor housing 21, an O-ring 22, an inner core 23 and a spindle 24 that is actuated from the outside of the apparatus to adjust the water flow rate, and the two joining in an outlet passage 28. As each control section respectively controls 50% of the water flow by the adjustment of the shaft 24, a good characteristics can be obtained such as a wide variable range of the water flow rate and a large water pressure change. |
