Pressure relief or control valve concept · 模型 170917
Conceptual design for a theoretical hydraulic circuit pressure relief or pressure control valve which I came up with back in the second half of 2013. I've improved the original CAD model from 2013 a little bit before uploading it here. I redid the threads, applied some more fillets to a few more edges and corrected some minor issues with the model. To the best of my knowledge, this has never actually been tried or tested for viability, efficacy or safe or reliable operation. I'm not aware of this specific design having ever been produced, tested or evaluated in any way. Though I have submitted the design to various companies in the past, none of them appeared to show any interest in the idea. The design is not patented. The innovative aspect of this valve is that it should require very little force to open as the plug (the yellow piece in the renders) doesn't need to open against a pressure gradient and doesn't need to reduce (even by a minute amount) the internal volume of the valve's main chamber or the hydraulic or high pressure fluid circuit the valve is connected to, in order to open. At the same time, the valve can also not be opened by the pressure in the circuit it's connected to. This is because its obstructing element, in addition to not having to open against a pressure gradient, also doesn't need to resist a pressure gradient to stay closed either. The valve opens by retracting the plugging element (the yellow component in the renders) from the outlet duct in the valve's body, which it inserts into from the valve's main chamber. This allows fluid from the valve's main chamber (and whichever hydraulic or high pressure circuit it is connected to) to escape through the outlet channel. The plugging pin is advanced forward and kept in position by way of actuation by a solenoid (depicted in brown in the renders), which is situated in a different chamber of the valve, on the opposite side of the valve body (pictured in blue in the renders) from the outlet duct and isolated from its main chamber by a wall with a hole in it for the pin to pass into the main chamber through and continue on into the outlet channel. The valve body (represented in blue in the renders) would need to be precisely machined to very tight tolerances so as to avoid leakage, between itself and the obstructing pin, from the valve's main chamber and either into the outlet channel or into the solenoid (depicted in brown in the renders) housing chamber, which are on opposin...
