A planar torsion spring where the spring comprises a first outer ring and a second inner ring. The inner ring is positioned within the first outer ring and possesses a same axis of rotation. The outer ring is connected to the inner ring with one or more splines. Each spline extends in one or more concentric arc segments to a maximum circumference relative to the position of the next concentric arc between the outer ring and the inner ring. The outer ring, the inner ring and the spline concentric arcs segments are positioned in the same plane. At least one spline connects the outer ring to the inner ring. The spline is positioned in a plurality of concentric arcs segments and sequentially positioning each arc to a maximum circumferential length relative to its position between the outer ring and inner ring.

A planar flexure member for resisting rotation about a central axis thereof includes, in various embodiments, a central portion (215) comprising a plurality of attachment points (217); and at least one serpentine flexure arm (220a,220b) extending from the central portion in a plane. The arm(s) terminate in an arcuate mounting rail (225a, 225b) that includes a series of attachment points (217). The rails may be positioned in opposition to each other to partially define and occupy a planar circular envelope radially displaced from but surrounding the central portion of the flexure member. A portion of the serpentine arms may extend to (or substantially to) the envelope between the mounting rails.

The invention provides a reciprocating linear compressor and an inner exhaust tube set thereof. The inner exhaust tube set of the reciprocating linear compressor comprises a first tube section and a second tube section communicated with the first tube section through a first buffer. The second tube section is a spiral coil and extends in the axial direction. According to the inner exhaust tube set of the reciprocating linear compressor, the spiral coil has a buffering effect, so that vibration of the inner exhaust tube set is reduced, the probability that the inner exhaust tube set is broken due to vibration of a machine body is lowered, and influences on normal work of the reciprocating linear compressor are reduced. Meanwhile, the first tube section and the second tube section are communicated through the first buffer, the stress of a pipeline at the joint of the first tube section and the second tube section is effectively reduced, and the probability that the inner exhaust tube set is broken is lowered. Airflow pulses are also reduced, vibration of the inner exhaust tube set is reduced, flowing noise of air flow is also lowered, and the silencing function is achieved.

The utility model provides a linear compressor and have its refrigeration plant, this linearity compressor are including the first cylinder and second cylinder and corresponding first piston and the second piston that set up both sides in the casing, and through connecting piece fixed connection between first piston and the second piston, the inside of first piston, second piston and connecting piece has the hollow portion of mutual intercommunication, and linear motor makes first piston and second piston reciprocating motion and produce compressed gas in the compression chamber. The elastic component provides elastic restoring force to first piston and second piston. The compressed gas that treats who is got into by the gas access that sets up on the connecting piece distinguishes compressed discharge alternately. Get into the compression chamber owing to treat the connecting piece of compressed gas from two pistons of linear compressor between, can reduce and breathe in overheatedly, improved the volume efficiency of compressor, simultaneously because the stroke is little, two pistons longe -lived, the reliability improves. The utility model also provides a refrigeration plant who has above -mentioned linear compressor.

Linear compressor and have its refrigeration plant

The invention provides a plate spring. The plate spring comprises at least two spring arms and an inner fixing hole, wherein the at least two spring arms and the inner fixing hole are centrally and uniformly distributed; the structure of each spring arm is the same; the outermost end of each spring arm is provided with an outer fixing hole. The invention also provides the plate spring assembly and the compressor. The plate spring assembly comprises a plurality of plate springs. The compressor comprises the plate spring assembly. According to the plate spring, the structure of multiple concentric circular arms and a concentric spiral arm is adopted; the plate spring has smaller equivalent mass, and the situation that parts are increased to meet the requirements on rigidity and natural frequency is avoided, so that the product quality is reduced and the cost is reduced.
