Abstract
A linear compressor disclosed herein includes a cylinder whose axial direction is directed to a horizontal direction. The linear compressor comprises a cylinder supported in a hermetic vessel by a supporting mechanism, a piston slidably supported along an axial direction of the cylinder concentrically with the cylinder, and a linear motor for generating thrust force by forming a magnetic passage by a movable portion secured to the piston and a stationary portion secured to the cylinder. The supporting mechanism comprises first and second coil springs supporting the cylinder from its opposite ends in the hermetic vessel, and at least one of the first and second coil springs comprises a plurality of coil springs which are juxtaposed to each other.
Claims16
A linear compressor comprising a cylinder supported in a hermetic vessel by a supporting mechanism, a piston slidably supported along an axial direction of said cylinder concentrically with said cylinder, and a linear motor for generating thrust force by forming a magnetic passage by a movable portion secured to said piston and a stationary portion secured to said cylinder, wherein said supporting mechanism comprises first and second coil springs supporting said cylinder from its opposite ends in said hermetic vessel such that substantially a same load is applied to each of the first and second coil springs, and at least one of said first and second coil springs comprises a plurality of coil springs which are juxtaposed to each other.
A linear compressor comprising a cylinder supported from its opposite ends in a hermetic vessel by a supporting mechanism, a piston slidably supported along an axial direction of said cylinder concentrically with said cylinder, and a linear motor for generating thrust force by forming a magnetic passage by a movable portion secured to said piston and a stationary portion secured to said cylinder, wherein said cylinder is formed at its one end with a compressing chamber, said linear compressor further comprises a discharge tube for discharging refrigerant compressed in said compressing chamber out from said hermetic vessel, said discharge tube is wound, into a spring shape, around an outer periphery of one end of said supporting mechanism, and spring constant of said one end of said supporting mechanism is set greater than that of said discharge tube.
A linear compressor comprising a cylinder resiliently supported in a hermetic vessel, a piston slidably supported along an axial direction of said cylinder concentrically with said cylinder, and a linear motor for generating thrust force for reciprocating said piston in its axial direction by forming a magnetic passage by a movable portion secured to said piston and a stationary portion secured to said cylinder, so that lubricant is contained in said hermetic vessel, wherein said cylinder is provided at its lower portion with a lubricant supplying apparatus, said lubricant supplying apparatus supplies lubricant retained in a bottom of said hermetic vessel to sliding surfaces between said piston and said cylinder.
A linear compressor comprising a cylinder supported in a hermetic vessel by a supporting mechanism, a piston slidably supported along an axial direction of said cylinder concentrically with said cylinder, a linear motor for generating thrust force by forming a magnetic passage by a movable portion secured to said piston and a stationary portion secured to said cylinder, and a lubricant supplying means disposed in a lower portion of said cylinder for supplying lubricant to sliding surfaces between said piston and said cylinder by vibration of said cylinder, wherein said supporting mechanism comprises first and second coil springs supporting said cylinder from its opposite ends in said hermetic vessel, and at least one of said first and second coil springs comprises a plurality of coil springs which are juxtaposed to each other.
