Murdoch 2 Cylinder Vertical oscillator

Description

Norbert Keeley designed this engine in the early 1970’s. It comes in a single cylinder and 2 cylinders (Double Murdock).

An oscillating cylinder steam engine (also known as the wobbler in the US) is a simple steam-engine design (proposed by William Murdoch at the end of 18th century) that requires no valve gear. Instead, the cylinder rocks, or oscillates, as the crank moves the piston, pivoting in the mounting trunnion so that ports in the cylinder line up with ports in a fixed port face alternately to direct steam into or out of the cylinder.

Oscillating cylinder steam engines are mainly used in toys and models but, in the past, have been used in full-size working engines, mainly on ships and small stationary engines. They have the simplicity and therefore, low manufacturing costs.
