Embodiment Construction

[0056] figure 1 A sectional view of a device 1 according to the invention is shown with a linear drive 2 and a linear compressor 3 . The linear drive 2 has a stator 4 , wherein a rotor 5 moves in a reciprocating manner along a drive axis 9 . The rotor 5 is driven by means of drive coils 16 which are supplied with drive coil current by means 17 for actuating the drive coils 16 .

[0057] The rotor 5 oscillates between a first rotor reversal point 11 and a second rotor reversal point 12 and in doing so passes through a rotor zero position 13 . The movement of the rotor 5 is sensed by means of a position sensor 25 which transmits position information to the means 17 for actuating the drive coils 16 , as a result of which a control system is implemented for the movement of the rotor 5 as a whole.

[0058] The linear compressor 3 has a piston housing 7 in which the compressor piston 6 oscillates in a reciprocating manner along the piston axis 8 between a first piston reversing po...

Abstract

The invention relates to an apparatus (1) comprising a linear drive (2) which has a stator (4) and a rotor (5) movable in a reciprocating manner therein along a drive axis (9) between a first (11) and a second (12) rotor reversal point about a rotor zero position (13), and/or comprising a linear compressor (3) which has a piston housing (7) and a compressor piston (6) which is movable in a reciprocating manner therein along a piston axis (8) and a first (21) and a second (22) piston reversal point about a piston zero position (23) and can be driven by the linear drive (2), wherein either the rotor zero position (13) or the piston zero position (23) is adjustable and/or at least one spring element (14, 15) acts on the rotor (5) or on the compressor piston (6), the length of which can be varied, in particular shortened, and/or the spring constant of which can be changed, in particular increased; and a method for cooling commodities (27) or for compressing a fluid (18). The invention is distinguished by the fact that adaptation of the output delivered by the apparatus has no substantial effect on the electromechanical efficiency of the apparatus, as a result of which a linear drive (2) and a linear compressor (3) can be constructed in an especially cost-effective manner, since the diversity of the products can be considerably reduced.
