Title:
REVERSING VALVE WITH FLOWSPLITTER
Document Type and Number:
WIPO Patent Application WO2006028671
Kind Code:
A3
Abstract:
Provided is a reversing valve for reversing flow in a refrigeration system. The reversing valve includes a valve body having first, second, third, and fourth ports disposed into the valve body. A valve member inside the valve body can be selectively moved between a first position intersecting the second and third ports and a second position intersecting the second and fourth ports. The valve member defines a channel that directs flow between the selected pairs of ports. The channel is generally shaped as a curve that bends the flow between the selected ports. To reduce the pressure drop across the reversing valve, a flow splitter is included that divides the channel into multiple sub-channels. Dividing the channel into multiple sub-channels increases the curve ratio of the channel, which reduces the generation of turbulent secondary flows in the channel. The flow splitter also provides additional structural support to the valve member.
