    Abstract: A diaphragm pump may comprise a housing defining a first pumping chamber, a second pumping chamber, and a hydraulic fluid chamber, a first flexible diaphragm separating the first pumping chamber from the hydraulic fluid chamber, a second flexible diaphragm separating the second pumping chamber from the hydraulic fluid chamber, a rod mechanically linking the first flexible diaphragm and the second flexible diaphragm such that an expansion of one of the first and second flexible diaphragms exerts a contraction force on the other of the first and second flexible diaphragms, and a piston disposed within the hydraulic fluid chamber and configured to reciprocate to cause a hydraulic fluid contained within the hydraulic fluid chamber to alternately exert an expansion force on the first and second flexible diaphragms.

    Abstract: A coolant compressor has a hermetically sealed compressor housing, in the interior of which lies a piston cylinder unit that compresses a coolant. The cylinder housing of the piston cylinder unit is closed at the front end thereof by a cylinder head. A linear drive is provided, comprising at least one oscillating body which is surrounded by an excitation winding and which is connected to the piston to move same along a longitudinal axis in an oscillating manner. The piston cylinder unit has at least one first permanent magnet that lies on the piston, and at least one second permanent magnet that lies on the cylinder housing. Both magnets face each other and are oriented in the same magnetic pole direction in order to generate a repelling effect between both magnets to limit the path of the piston in the region of the top or bottom dead center.

    Abstract: An apparatus and method for controlling an operation of a reciprocating compressor are disclosed in which a point of inflection with respect to an operation frequency of the reciprocating compressor is detected at a point of time when a phase difference between current and stroke is uniformly maintained, and an operation of the reciprocating compressor is controlled upon recognizing the detected point of inflection with respect to the operation frequency as a point TDC=O. The apparatus for controlling an operation of a reciprocating compressor includes: a control unit for detecting a phase difference between current and stroke and outputting a frequency inflection point detect signal or a frequency variable signal; and a stroke reference value control unit for determining whether a frequency inflection point has been detected or not according to the frequency inflection point detect signal and outputting a stroke reference value control signal based on the determining result.

    Abstract: An apparatus and method for controlling an operation of a reciprocating compressor are disclosed. The apparatus for controlling an operation of a reciprocating compressor includes: a TDC/BDC detecting unit for detecting a TDC and a BDC of the reciprocating compressor; and a controller for independently controlling the TDC and the BDC so as to fit each reference position based on the detected TDC and BDC. Efficiency of the reciprocating compressor can be enhanced by independently controlling a top dead center and a bottom dead center.

    Abstract: A free-piston linear compressor (1) controlled to achieve high volumetric efficiency by a controller including an algorithm (116) for ramping up input power until piston-cylinder head collisions are detected using a detection algorithm (117/118) which then decrements power input whereupon input power is again ramped up by algorithm (116). Non-damaging low energy collisions are achieved by the controller including a perturbation algorithm (119) which perturbates the input power ramp with periodic transient pulses of power to ensure piston collisions are provoked during the transient power pulses.
