Abstract
Spark plug assemblies and turbomachines are provided. A spark plug assembly includes a monolithic hollow cylinder extending along a longitudinal axis between a first end and a second end, the monolithic hollow cylinder including a sidewall defining an interior, a first end wall, and a second end opening. The first end wall defines a first end opening at the first end. The second end opening is defined at the second end. The spark plug assembly further includes an igniter assembly extending along the longitudinal axis into the interior through the first end opening and from the interior through the second end opening. The spark plug assembly further includes a piston surrounding the igniter, the piston disposed within the interior and extending from the interior along the longitudinal axis through the second end opening.
