Abstract

A hermetic refrigeration compressor has a cylinder block and a crankshaft rotatable about a vertical axis to reciprocate a piston in a cylinder on the cylinder block. A separate bearing housing is secured to the central portion of the cylinder block and extends vertically along the crankshaft, where it carries a pair of roller bearings to journal the crankshaft. The crankshaft has a radially extending flange which is journaled by a thrust-type roller bearing above the bearing housing to absorb the vertical forces on the crankshaft so that all three of the roller bearings are between the crankshaft and the bearing housing to maintain and control the close tolerances required by such bearings.

Patent Kohno, K; Takubo, H; Ito, T

An internal combustion engine is described including cylinder block means having inner wall means defining at least one cylinder bore, outer wall means provided outside the inner wall means and defining cooling water jacket means with the inner wall means, deck means provided below and continuous with the outer wall means to provide at least partly an upper part of crankcase means, a piston disposed in the cylinder bore for reciprocating movements, crankshaft means disposed in the crankcase means and connected with the piston means so that a reciprocating movement of the piston is converted into a rotation of themore »« less
Compression ratio control in reciprocating piston engines

Patent Doundoulakis, G

The patent describes compression ratio control for reciprocating piston engines. It comprises: a reciprocating engine crankcase; a plurality of compression/expansion cylinders rigidly attached to the crankcase; each of the cylinders including a curved surface and a cylinder head; a fuel mixture in-taken in the cylinders; a piston reciprocating along each cylinder's curved surface for providing compression/expansion to the fuel mixture; a crank mechanism including a crankshaft rotating about an axial line that is substantially equidistant from the heads, crankcheek lobes radially extending from the crankshaft, crankpins inside and in contact with crankpin bearings, axially extending between the crankcheek lobes, andmore »« less
