An opposed piston gamma type Stirling machine has its displacer driven by a linear electromagnetic transducer that is drivingly linked to the displacer and is located on the opposite side of the power piston's axis of reciprocation from the displacer preferably in the bounce space. The linear transducer is controlled by an electronic control as a function of sensed inputs of Stirling machine operating parameters. In addition to allowing improvements in stability and efficiency, such a Stirling machine operated as a cooler/heat pump can also be controlled so that its displacer can be driven at (1) a phase angle that pumps heat in one direction through the machine or (2) at another phase angle that pumps heat in the opposite direction through the machine and allows selectively switching between the heat pumping directions.
An opposed piston, gamma configured, controllable, free-piston Stirling machine having an outer casing and a work space within the casing, the work space including an expansion space and a compression space, the Stirling machine comprising:
A Stirling machine in accordance with 2 claim wherein the rod is a connecting rod having no drive rod and all power driving the displacer in reciprocation is applied from the electromagnetic linear transducer.
In a Stirling cooler/heat pump having a power piston and a displacer separating a work space into a first space in thermal connection to a first heat exchanger and a second space in thermal connection to a second heat exchanger, a method for operating the Stirling cooler/heat pump for optionally and selectively pumping heat from the first heat exchanger to the second heat exchanger or alternatively from the second heat exchanger to the first heat exchanger for selectively heating or cooling an object in thermal connection to one of the heat exchangers, the method comprising:
