Bypass valve assembly with integrated flow control valve

A bypass valve assembly comprising:

• a housing including an inlet, an outlet, a flow passageway fluidly connected to said inlet and said outlet to allow flow of a liquid from said inlet to said outlet, and a valve seat disposed about said flow passageway between said inlet and said outlet;
• a movable poppet disposed in said housing to engage said valve seat in a closed position and to disengage said valve seat in an open position when pressure of the liquid in said flow passageway exceeds a preset value to allow flow of the liquid through said flow passageway from said inlet to said outlet;
• a flow control valve disposed rotatably in said housing between said inlet and said outlet, said flow control valve including a fluid passage having a first section and a second section, said second section having an axial width greater than an axial width of said first section;
• a selector lever operatively coupled to said flow control valve to manually move said flow control valve;
• a lever plate coupled to said housing and cooperating with said selector lever to define a plurality of predefined positions for said selector lever to control flow of the liquid between said inlet and said outlet when said poppet is engaged with said valve seat in said closed position;
• and
• an intermediate adjustable plate coupled to said lever plate to receive said selector lever in said variable position to allow said fluid passage of said flow control valve to be adjusted to correspond to a desired level of flow and be secured in said variable position relative to said lever plate.

• a flow control valve rotatably disposed in said housing between said inlet and said outlet and fluidly communicating with said flow passageway, said flow control valve including a fluid passage having a first section and a second section, said second section having an axial width greater than an axial width of said first section;
• and
• a rotary actuator coupled to said flow control valve to automatically move said flow control valve to control flow of the liquid between said inlet and said outlet when said poppet is engaged with said valve seat in said closed position.
