Title:
【発明の名称】流体混合弁
Document Type and Number:
Japanese Patent JP2742932
Kind Code:
B2
Abstract:
An adjustable ratio mixing valve is disclosed which incorporates an automatic pressure compensating arrangement whereby the fluid pressure immediately upstream of each of the metering orifices is maintained in substantial equilibrium. This arrangement then enables the respective fluids to be intermixed in any desired volumetric ratio by merely suitably adjusting the open flow area of the metering orifices. In one embodiment the metering orifices are each externally adjustable to enable relatively easy changes in the mixing ratio to be made and may also be interconnected whereby flow volume may be changed while maintaining the desired present mixing ratio. In another embodiment, rapidly acting on/off valving is provided integral with the valve so as to render it uniquely suited for cyclic fluid flow.
