High response solenoid valves?????
High response solenoid valves?????
(OP)
I have a unique application for a high repsonse solenoid valve. I'm using it to open the throttle on a race car. in this application there are two critical things. 1) response time 2) flow. Can anyone point me in the right direction of a high response high flow valve??? Here are my system limits.
Cylinder: 1"bore x 3" stroke
Working pressure: 300psi
force to over come: < 10 lbf
Actuation voltage: 12 - 18 VDC
Amperage Draw: unlimited (for argument sake)
Weight: as light as possible
I'm looking for response times below .001 sec

I think you ought to set more realistic goals.

Why did you give the Cylinder dimension? How it is affects the solenoid? What is the throttle diameter?
The electrical response time for 18V will be 1.5 faseter than the 12V.

What is the mass of the moving part of the solenoid?

That's awful fast. Does it just need to react that fast, or go to full opening? This will be like hitting your throttle linkage with a hammer. That's it...hook a nail gun to it

I always thought race cars would prefer mechanical throttles. Push the pedal, the rods move, something opens ...

You don't spec speed of solenoid for your problem. You spec the overall speed of response. It makes no sense at all to say " I want a solenoid with a minimum of 1msec response". You are interested in finding a solenoid which when coupled to your mechanical linkage will give a reasonably fast response. You start out by looking for one whose inertial load is similar to that of the linkage load and then drive it with a current source, neaning you put an enormous voltage on the solenoid for a controlled minimum time to increase the electrical response thus overcoming the inductance of the solenoid. Then you make a determination of whether this is what you want. In any event, you wont drive a mechanical system like yours in 1 msec. You are moving mechanical mass, not electrons.

In either case, a solenoid is pretty much an on/off or open/closed device. Not really the ideal thing if you need to modulate throttle position.
Can your engine go from idle to full throttle in 1 msec? There is no point in having a throttle that is more responsive than your engine?
