In a plain bearing assembly, excess lubricating oil is delivered from one region of clearance space to another to inhibit transverse vibration of a journal relatively to an outer bearing member. In an embodiment, the journal 1 is in a housing formed of upper and lower members 2, 3 and the clearance between the journal and the housing is connected by conduits 4 which serve as a restricted flow path for the lubricant and which connect to a restrictor 7. The housing has axially-spaced annular recesses 8 therein with an annular oil-groove 9 therebetween which receives oil through a port 11 in the housing. The lower member 3 has a pair of axially-spaced oil-grooves 12 which are connected, via passages 14, to a relief valve 13 which releases any excess pressure developed in the bearing. In use, when the journal vibrates the oil is forced through the restrictor 7 and energy is absorbed so that the vibration of the journal is damped. The recesses 8 serve as oil reservoirs and also allow a flow of oil from a decreasing clearance space to an increasing clearance space. In another embodiment, the inner bearing surface of the housing is in the form of a pair of spiral surfaces, each extending angularly through 180 degrees and each of which begins and ends at a step, the steps being diametrically opposed and positioned in the plane of the joint faces.

Fluid-pressure engines. - In internal - combustion engines of the kind wherein the combustion chamber is arranged wholly or mainly at one side of the axis of the cylinder and is partly in the cylinder block and partly in the removable head, the combustion chamber is formed by means of a rotary milling cutter having a curved end surface which forms part of a sphere. When the inlet and exhaust valves are situated in the cylinder block and cylinder heads, the combustion chamber is formed by a milling-cutter f, Fig. 1, having a spherical end surface and a periphery of circular or other curved cross section. The cylinder block and head are operated upon separately and relative arcuate movement between the cutter and work is produced about centres g, k in each case to generate the surfaces i, j, the centres being the centres of curvature of the spherical surfaces on the cutter and being situated on the centre lines of the valves h, l. When the two valves are situated side by side in the same part e.g. the cylinder block, the cutter is caused to make two intersecting cuts in each part, a centre on each of the valve centre lines being used for the relative arcuate movements. The intersecting cuts form a combustion chamber of the shape shown in plan in Fig. 5, wherein the full line n shows the shape in the cylinder block and the line n and dotted line o together show the shape in the cylinder head. The plane containing the major axis of the combustion chamber is at right angles to the axis of the valves and the cutter may have a cylindrical or other periphery to produce a straight or other shaped end wall i of the chamber.
