| In an internal-combustion engine, the light-metal cylinder head 1 is bolted together with the cylinder crankcase 2 by means of bolts 9, which extend in each case through a bore hole 10 in the cylinder head 1 and are bolted into a threaded borehole 11 in the cylinder crankcase 2. In order to keep the surface pressure, when the cylinder head bolts are tightened, at a level permissible for the light-metal alloy of the cylinder head 1 without using shims that require much space, a threaded sleeve 15 of steel, on the face 17 of which the head of the cylinder head bolt 9 is lying, is screwed into the borehole 10. The bearing surface for the force of the bolt is formed by the areas of the edges of the thread of the threaded sleeve 15. Accordingly, a sufficient area can be made available by an appropriate number of threads without the need to have the external diameter of the threaded sleeve 15 larger than the external diameter of the bolt head 12, 13. | ||||||

| A sacrificial body mitigates cavitation damage to components within a pump. The sacrificial body is mounted in the pump so that flowing fluid passes over the sacrificial body, which causes the sacrificial body to shed electrons into the flowing fluid in the vicinity of the cavitation. The excess electrons tend to suppress hydrogen ions from releasing, which can mitigate cavitation. The sacrificial body is formed of a material having less resistance to corrosion due to the flowing fluid than the components of the pump. Needles are attached to the sacrificial body for immersion in the flowing fluid to facilitate the release of the electrons for the sacrificial body. | ||||||

| A method for producing a cast combination of cylindrical hollow profiles and for casting said combination into a cylinder block or crank housing of an internal combustion engine, wherein cylindrical hollow profiles consisting of a light-metal alloy and containing inlaid hard phases that have been manufactured by successive stages of spray compacting, hot extrusion and hot forming are arranged in a row, the distance between the axes of the hollow profiles corresponding to the cylinder bore center distance of the cylinder block and a light-metal alloy without inlaid hard phases is cast around said profiles. The cast combination is then positioned in a mould that forms the cylinder block and a light-metal material is cast around said combination. | ||||||

| An aluminum cylinder block (1) of an engine has a plurality of cylinder bores (2), and intermediate marginal areas (17) defined between adjacent cylinder bores (2). A single water jacket (8) is formed in the cylinder block (8) to surround the plurality of cylinder bores (2), and a plurality of oil chutes (15) are also formed in the cylinder block (1) outside the water jacket (8) for allowing an oil to drop from a cylinder head (5) to a crankcase (14) therethrough. These oil chutes (15) are formed between adjacent intermediate marginal areas (17) so that they do not make the cylinder block (1) swell out. An air in the oil chutes (15) functions as a sound insulation layer against combustion noises generated in the cylinder bores (2). The air in the oil chutes (15) also serves as a heat insulation layer for a cooling water in the water jacket (8) so that warming up performance of the engine under a cold condition is improved. | ||||||

| A two-stroke, U-type uniflow engine includes a cylinder block forming parallel first and second cylinders and a common combustion chamber connecting the first and second cylinders. First and second pistons are mounted for reciprocal, linear movement within the first and second cylinders respectively. The engine also includes a crank shaft having a crank pin and a one-piece forked connecting rod connecting each of the first and second pistons to the crank pin. The connecting rod is elastically, bilaterally flexible to accommodate variations between a maximum distance between the first and second pistons and a minimum distance between the first and second pistons and is in a relaxed state half-way between the maximum distance and the minimum distance. The central wall has a slot for passage of the connecting rod therethrough and angled notches which correspond to maximum angles of the connecting rod. The connecting rod is designed to minimize weight and length and the engine bore and stroke are selected to minimize the difference between the maximum and minimum distance of the wrist pin displacement in order to reduce vibrations and to increase engine output by maintaining high crankcase compression. | ||||||

| PROBLEM TO BE SOLVED: To solve the following problem: in the conventional vane rotary compressor, when a compressed refrigerant is discharged from an operating chamber in a cylinder through a discharge hole to outside the cylinder, a discharge valve closes the discharge hole before all the high pressure refrigerant is discharged, and for this reason, some high-pressure refrigerant stays inside the discharge hole, and therefore when the discharge hole communicates with the operating chamber which performs the next discharge operation, the high-pressure refrigerant staying in the discharge hole flows back into the operating chamber, and is re-expanded and re-compressed, resulting in a deterioration in efficiency.SOLUTION: In a vane rotary compressor, a discharge valve is provided on a discharge flow channel communicating an operating chamber in a compression element with a discharge hole. The discharge valve is pushed from an opening portion of a discharge valve groove to an outer circumferential surface of a roller by a high-pressure refrigerant when pressure in the operating chamber is lower than the pressure of the high-pressure refrigerant. The discharge valve is pushed back into the discharge valve groove by the refrigerant pressure in the operating chamber when the pressure in the operating chamber is higher than the pressure of the high-pressure refrigerant. The discharge flow channel is closed by the outer circumferential surface of the discharge valve pushed out from the opening portion of the discharge valve groove and the outer circumferential surface of the roller, and opens when the discharge valve is pushed back into the discharge valve groove. | ||||||
