2 Cylinder Sliding Valve Engine

prusaprinters

<p>Building off of my earlier sliding valve air engine( <a href="https://www.thingiverse.com/thing:2492963">https://www.thingiverse.com/thing:2492963</a>), here is a 2 cylinder version. This design runs well, but it needs lots of air.</p> <p>Included in the files is a list of parts and hardware - See BOM_list.pdf. There are also pictures to help set the eccentric orientation during assembly.</p> <p>Also a .step file is included if you want to make changes.</p> <p>Slider_3 was optimized for the single cylinder engine and may be a better option for this engine too. It works well with Slider_2</p> <p>Here are a couple videos of the engine in action.</p> <p> <figure class="media"> <oembed url="https://youtu.be/QOqWBn9rho0"></oembed> </figure> </p> <p> <figure class="media"> <oembed url="https://youtu.be/rPLHXZ8i-B4"></oembed> </figure> </p> <h3>Print instructions</h3><p>Unassociated tags: air powered, sliding valve, steam engine</p> <h3>Category: Mechanical Toys Print Settings</h3> <p><strong>Printer Brand:</strong> Prusa</p> <p><strong>Printer:</strong> I3 MK3S</p> <p><strong>Supports:</strong> Yes</p> <p><strong>Infill:</strong> Varies</p> <p><strong>Notes:</strong></p> <p>Support where needed, many parts don't need it.</p> <p>Infill 100% on rotating components for sure. Flywheels need the mass.</p> <p>Printed this in PLA for a fit and function test, seems to work ok.</p>
