Abstract
A system, in certain embodiments, includes a barrier with magnetic coupling between opposite sides of the barrier. For example, the system may include a first member with a first magnet that translates along with the first member, and a second member having a second magnet that translates along with the second member. The system also may include the barrier completely isolating the first member from the second member, wherein the first magnet magnetically couples with the second magnet through the barrier to impart translational motion from the first member to the second member.
Claims18
A system, comprising:
- a compressor;
- a crankshaft;
- a motor coupled to the crankshaft;
- a first member coupled to the crankshaft, wherein the first member comprises a first magnet that translates along with the first member;
- a piston;
- a second member coupled to the piston, wherein the second member comprises a second magnet that translates along with the second member;
- and
- a barrier completely isolating the first member from the second member, wherein the first magnet magnetically couples with the second magnet through the barrier to impart translational motion from the first member to the second member.
A system, comprising:
- a first reciprocating member having a first magnet, wherein the first magnet is configured to transfer reciprocal motion of the first reciprocating member to a second reciprocating member via a second magnet coupled to the second reciprocating member, and wherein the first reciprocating member comprises a connecting rod configured to couple with a crankshaft.
A system, comprising:
- a magnetic coupling barrier configured to completely isolate first and second members on opposite sides of the magnetic coupling barrier, wherein the magnetic coupling barrier is configured to enable magnetic coupling and transfer of translation motion between first and second magnets coupled to the respective first and second members, and wherein the magnetic coupling barrier comprises a can-shaped geometry having an annular wall and a closed end, and the magnetic coupling occurs through the annular wall, the closed end, or a combination thereof.
A system, comprising:
- a drive;
- a crankshaft coupled to the drive, wherein the drive is configured to rotate the crankshaft;
- a first reciprocal shaft coupled to the crankshaft, wherein the first reciprocal shaft comprises a first annular magnet;
- a second reciprocal shaft having a second annular magnet;
- a piston coupled to the second reciprocal shaft;
- a gas compression chamber disposed adjacent the piston;
- and
- a can-shaped barrier in a fixed position that isolates the first and second reciprocal shafts, wherein the can-shaped barrier completely blocks gas from leaking from the gas compression chamber to an opposite side having the first reciprocal shaft, the first annular magnet magnetically couples with the second annular magnet through an annular wall of the can-shaped barrier to impart reciprocal motion from the first reciprocal shaft to the second reciprocal shaft.
