Stirling cycle machine. The machine includes at least one rocking drive mechanism which includes: a rocking beam having a rocker pivot, at least one cylinder and at least one piston. The piston is housed within a respective cylinder and is capable of substantially linearly reciprocating within the respective cylinder. Also, the drive mechanism includes at least one coupling assembly having a proximal end and a distal end. The linear motion of the piston is converted to rotary motion of the rocking beam. Also, a crankcase housing the rocking beam and housing a first portion of the coupling assembly is included. The machine also includes a working space housing the at least one cylinder, the at least one piston and a second portion of the coupling assembly. An airlock is included between the workspace and the crankcase and a seal is included for sealing the workspace from the airlock and crankcase. A burner and burner control system is also included for heating the machine and controlling ignition and combustion in the burner.
A method for controlling the pressure difference between an airlock having a gas at an airlock pressure and a crankcase having a gas and liquid at a crankcase pressure, the crankcase containing a drive mechanism, the method comprising:
A method for controlling the pressure difference between an airlock having a gas at an airlock pressure and a crankcase having a gas and liquid at a crankcase pressure, the crankcase containing a drive mechanism, a two way pressure regulator configured to fluidly connect the airlock to an outlet of a compressor, the crankcase workspace or nothing, the two way pressure regulator comprising a spool valve, where the position of the spool valve is responsive to the pressure difference between the airlock pressure and the crankcase pressure, the method comprising:
