摘要： A method for mechanically roughening a cylindrical surface of a workpiece, e.g. the piston-bearing surface of a cylinder sleeve in a cylinder crankcase, by producing a defined microstructure of mutually crossing grooves, and by a groove forming tool, operating with or without material removal. A method in which in a first operation, a groove-forming tool is moved axially along the workpiece surface in such a way that at least one axial groove is machined into the workpiece surface; and in a second operation, following the first operation, the groove forming tool is rotated about the cylinder axis by a predefined rotational angle in the axial position reached in the first operation, whereby at least one circumferential groove crossing the axial groove is machined into the workpiece surface; and in a third operation following the second operation, the groove-forming tool is drawn back axially along the workpiece surface.

摘要： A flow restrictor (1) for use in bearing formation between a piston (2) and a cylinder (3) of a gas compressor (4). The gas compressor (4) includes a protective pad (5) that externally surrounds the cylinder (3), and an inner cavity (6) is disposed between the protective pad (5) and the cylinder (3), fluidly fed by a discharge flow from a compression movement exerted by the piston (2). The gas compressor (4) further includes a bearing formation gap (7) that separates an outer wall of the piston (2) and an inner wall of the cylinder (3). A flow restrictor (1) is provided with a housing (12) that fluidly associates the inner cavity (6) to the bearing formation gap (7). The flow restrictor (1) includes a limiting tube (8) associated with the housing (12), provided with at least one restraining portion provided with a cross section sized to limit the gas flow from the inner cavity (6) to the bearing formation gap (7).

摘要： The invention proposes a piston (10) for an internal combustion engine, having a piston crown (11), having a fire land (12), having an encircling ring section (13) which has annular grooves (14), and having a piston shank (15) which has two shank walls (16, 17) arranged on the pressure side (DS) and on the counterpressure side (GDS) and two box walls (18, 19) which connect the shank walls (16, 17) to one another, wherein the box walls (18, 19) are provided with pin hubs (21) which have hub bores (22), and wherein the shank wall (16) arranged on the pressure side (DS) is shorter, as viewed in the circumferential direction of the piston (10), than the shank wall (17) arranged on the counterpressure side (GDS). To reduce the loading of the piston, the pressure-side box walls (18) run rectilinearly and obliquely, wherein the spacing of the box walls (18) is greater in the region of the pin hubs (21) than in the region of the pressure-side shank wall (16).

摘要： The present invention utilizes rolling elements, such as balls or rollers acting as bearings carried in openings in the skirt or equivalent portion of a piston, to engage the cylinder walls and replace the sliding bearings of the skirt with the roller elements in the skirt. The rolling elements then absorb all or some of the thrust loads conventionally absorbed by the skirt walls sliding along surfaces of an associated cylinder and thereby reduce the friction forces developed by the reciprocating action of the piston skirt.
