  • Patent number: 10041384
    Abstract: A control valve includes a valve housing extending along a longitudinal axis. The valve housing defines an inlet port, a first outlet port, and a second outlet port. In addition, the control valve includes a spool guide disposed inside the valve housing and a flow guide belt disposed around the spool guide. The flow guide belt is disposed inside the valve housing. The control valve further includes a spool movably disposed in the spool guide. The spool can move relative to the valve housing along the longitudinal axis between a first spool position and a second spool position. The first outlet port is in fluid communication with the inlet port when spool is disposed in the first spool position.
