Problems solved by technology

[0006] Although it is also possible to realize a linear compressor with a single oscillating piston, in this linear compressor the transmission of the reaction force exerted on the frame to the holding device of the compressor is limited in such a way that the frame itself is relative to the holding The unit can be vibratingly suspended; however, this type of linear compressor requires multiple springs which make the assembly of the linear compressor time-consuming and expensive
[0007] A further problem in spring-loaded retaining devices is that most spring types, when they are configured to resist movement of the frame parallel to the direction of vibration of the vibrating body, can deform slightly transverse to this direction, whereby significant amplitudes of the frame can be excited. side-to-side yaw movement, as long as this yaw movement is not damped by additional laterally supported springs or by rail guides

Embodiment Construction

[0024] figure 1 The linear compressor shown in includes a sound-insulated housing, only one of the two shells 1 of which is partially shown in this figure. The shells are in contact with one another at a circumferential flange 2 and thus form a closed enclosure apart from passages (not shown) for the refrigerant suction line or pressure line. Formed on the flange 2 are collars 3 for securing the shells to each other and on a carrier, which is not shown in the figure and is not considered part of the compressor.

[0025] Formed on the inner wall of the shell 1 are four sockets for buffers 4 made of rubber, resilient foam or other shock-absorbing material, which can only be seen on the edge of the shell 1 facing the viewer of the two buffers. The buffers 4 each have a slot which receives an end section 6 of a spring arm 5 . The spring arms 5 are each part of a diaphragm spring punched in one piece from spring steel, said diaphragm spring being figure 2 Shown in top view.

Abstract

The invention relates to a linear compressor, comprising a rigid frame (11, 12, 13), on which an oscillating body (16) is mounted by at least one spring (9), such as to move back and forth, at least one electromagnet (14, 15), for driving the back and forth movement of the oscillating body (16) and a pumping chamber (13), forming part of the frame, in which a piston, connected to the oscillating body (16), may move back and forth. The frame (11,12, 13) is connected to a fixing body (1), for fixing the linear compressor to a support by means of a membrane spring (5, 7, 9), arranged perpendicular to the movement direction of the oscillating body (16), such as to be able to oscillate.

Description

technical field [0001] The invention relates to a linear compressor, in particular to a linear compressor suitable for compressing refrigerant in a refrigeration device. Background technique [0002] A linear compressor is disclosed by US 6 642 377 B2, which has: a pump chamber in which a piston can reciprocate; a frame fixedly connected to the pump chamber, and a The vibrating body is reciprocally held on the frame by at least one spring; and at least one electromagnet assembled on the frame is used to drive the reciprocating motion of the vibrating body. [0003] The vibrating force exerted by the magnets on the vibrating body produces a corresponding vibrating counterforce, which the frame exerts on the holding device to which it is fastened. If the counterforce of this chatter is not balanced, it can excite the holding device or other parts connected to the holding device to vibrate, which the user perceives as operating noise. [0004] In order to keep such vibrations...
