Title:
パイロット式の弁装置
Document Type and Number:
Japanese Patent JP4915753
Kind Code:
B2
Abstract:
A pilot-type water discharging/stopping and flow regulating valve device capable of performing both the discharging/stopping of water and the regulation of flow by light operations, and capable of, once the flow is regulated, discharging the water at a pre-regulated specified flow in the next water discharge even if the water is stopped. The pilot type water discharging/stopping and flow regulating valve device 10 has a main valve 20, a back pressure chamber 26, an introducing small hole 28, a pilot channel 30 and a flow regulating mechanism. The flow of the main channel is regulated by advancing and retreating the main valve 20 following the advance/retreat of a pilot valve 34. The valve device further has a water discharging/stopping switching mechanism that switches between the discharging and stopping of water by advancing and retreating the pilot valve 34 between a water discharge position and a water stop position. Furthermore, the flow regulating mechanism is configured to maintain the flow regulating position of the pilot valve 34 at a previously regulated flow regulating position when the water discharging/stopping switching mechanism causes the pilot valve 34 to perform water discharging operation after causing the pilot valve 34 to perform water stopping operation.
