Horizontal type vibrating compressor

In a horizontal type vibrating compressor having a cylindrical container defining a chamber and having a horizontally extending axis for accommodating a compressor unit having a horizontally extending axis, the container having a pair of closure members closing opposite axial ends of the container, each closure member spaced outwardly of opposite axial ends of the compressor unit, the container adapted to receive a lubricant therein adjacent the bottom of the chamber, the compressor unit defining a compressor chamber and including a horizontally extending pumping cylinder and a horizontally extending and movable pumping piston inserted into the pumping cylinder at a location of the compressor chamber, the compressor unit including a magnet and a coil adapted to be energized for vibrating movement with respect to the magnet to move the pumping piston horizontally, an improvement comprising:

• a sleeve-shaped cushioning member defining a cylindrical space and made of cushioning material connected to one of an inner surface of one closure member and a spacing opposite axial end of the compressor unit, said cushioning member disposed coaxially with the compressor unit axis;
• a pin-shaped supporting member connected to the other of the closure member inner surface and facing opposite axial end of the compressor unit, said pin-shaped supporting member extending coaxially with the compressor unit axis and received for horizontal movement in said cylindrical space of said cushioning member;
• a pre-compressed spring engaged between the closure member inner surface and the facing opposite axial end of the compressor unit whereby relative axial movement between the compressor unit and the container are restricted by a biasing force of said precompressed spring and an engagement between said pin-shaped supporting member and said cushioning member;
• and
• an air-oil mixture supplying conduit connected between a bottom of said container chamber and a top of said compressor chamber, said conduit made at least in part of braided fibers in said container chamber for admitting an air/mixture into said conduit through said braided fibers and having an end disposed above the portion of the compressor chamber where the pumping piston is inserted into the pumping cylinder.
