CYLINDER FOR RECIPROCATING-PISTON ICE, ITS APPLICATION AS CYLINDER TO HOUSE LARGE ENGINE PISTON AND METHOD OF LUBRICANT DISTRIBUTION IN SAID CYLINDER Russian patent published in 2014 - IPC F02F1/20 

FIELD: engines and pumps.

SUBSTANCE: invention may be used in piston engines. A piston engine cylinder 1 serves to house a piston 2 provided with a piston ring 3. The cylinder 1 has a groove 5 for a lubricant intake and distribution and a piston sliding surface 7. The said surface 7 extends from the TDC zone 8 to a row of cleaning grooves 6 arranged on the cylinder. The groove 5 is made on the sliding surface 7 and comprises the first and second parts. The first part comprises the first and second ends. The first end includes the first section exposed in the cylinder inner chamber. The second end includes the second section exposed in the cylinder inner chamber. The ssecond part has the second and third ends. The third end includes the third section exposed in the cylinder inner chamber. The first and third exposed sections are located below the piston ring 3 extending in the groove 5. The ssecond exposed section is located above the piston ring 3 fitted in the groove 5 to the lubricant channel between the cylinder inner chamber above the piston ring 3 and the cylinder inner chamber below the piston ring 3 at location of the piston ring 3 between one of the first or third exposed sections and the second exposed section. There are multiple slot grooves with their ends connected to make a continuous channel extending along the sliding surface 7. A lubricant bore 16 is located in the continuous channel. The invention covers the cylinder application as the cylinder to house the large engine piston and method of the lubricant distribution in the cylinder.

EFFECT: uniform distribution of the lubricant over the cylinder entire length, decreased consumption of the lubricant.
