What is an Evo system on a car?
Understanding E.V.O. systems. E.V.O. stands for Electronically Variable Orifice. This component is controlled by an electronic control module that reduces fluid pressure from the power steering pump to the steering gear at highway speeds. Improved high speed handling and road feel is the result.
What is an Evo power steering system?
E.V.O. stands for Electronically Variable Orifice. This component is controlled by an electronic control module that reduces fluid pressure from the power steering pump to the steering gear at highway speeds. Improved high speed handling and road feel is the result.
What is the evolut Pro+ valve design?
Today, the Evolut PRO+ valve design means no tradeoffs. It provides the lowest delivery profile and added surface area contact between the valve and the native aortic annulus to further advance valve sealing performance.
Why choose evolut TAVR?
In addition, our exceptional valve design is taking patient outcomes above and beyond — contributing to our industry-leading hemodynamics. The Evolut PRO+ system is the only TAVR platform indicated to treat annulus ranges up to 30 mm diameter and has the ability to treat the broadest annulus range* of any commercially available TAVR system.
What does Evo mean in trucks?
While vehicle manufacturer terminology may differ, a typical system works like this: At speeds below 40 MPH, the Electronic Variable Orifice valve (EVO) is completely open, allowing full hydraulic flow from the power steering pump through the steering unit for maximum power assist.
What is GM Evo?
GM ELECTRONIC VARIABLE ORIFICE (EVO) STEERING SYSTEM The vehicle's computer monitored vehicle speed and steering wheel action to activate and deactivate a solenoid on the steering pump that controlled fluid flow to the steering gear. At slow speeds the EVO solenoid is fully open making the steering easier.
What is an EVO solenoid?
The vehicle computer monitors vehicle speed and steering wheel action to activate and deactivate the solenoid located on the steering pump, controlling fluid flow to the steering gear. At slow speeds, the EVO solenoid is fully open making steering assist easier.
What is Evo on a rack and pinion?
E.V.O. stands for Electronically Variable Orifice. This component is controlled by an electronic control module that reduces fluid pressure from the power steering pump to the steering gear at highway speeds. Improved high speed handling and road feel is the result.
What is Evo bypass pipe?
The EVO actuator (bypass pipe) replacement pumps have a direct con- nection to the power steering pressure hose. The pumps with bypass pipes installed fit the same as the OE unit and function as a standard steering system would. Moving forward, all remanufactured EVO pumps will be built with the bypass pipe installed.
What causes steering malfunction?
Pump malfunctions, fluid leaks, blocked hoses, contamination of power steering fluid, or worn power steering belts are some specific factors that can contribute to steering system failure.
Where is the control valve of a power steering rack and pinion system located?
The rotary control valve is connected to a torsion bar that is part of the steering shaft. The rack-and-pinion steering gear hydraulic cylinder is part of the rack gear, and the control valve is connected by a torsion bar to the steering shaft.
Fluid Dynamics Studies
Finite Element Analysis programs were used to study the fluid dynamics and make changes to the valve geometry in order to optimize the Cv and eliminate turbulance caused by the seat being in the center of the flow path.
Features & Benefits
Pneumatic actuator built-in to the valve body making the complete envelope extremely compact, lightweight, and streamlined while using less air per cycle
