Title: Combustion engines sparking plug
Inventor: PELKA RADOSLAV
IPC: H01T13/54
Filed: 2010-07-12
Abstract: An internal combustion engines sparking plug according to the invention contains a solid housing (2), which is an electric and thermal conductor. In its interior recess, a gas-proof, ceramic insulator (1) is located with central electrode (3), whose protruding end is located inside a cylinder (17) of the sparking plug. The bottom part of the housing (2) of the sparking plug is a truncated cone, and the side streaming holes (5) are designed in a radial pattern around the sparking plug on the cone sheath, whilst the streaming holes (5) are inclined towards the vertical axis of the sparking plug at the angle of 45° to 90°. At least two side streaming holes (5) are designed in a radial pattern around the cone sheath perimeter of the sparking plug. In addition to that, the sparking plug may have a single vertical streaming hole (13) and (16) in the mass electrode (10) of the sparking plug, designed coaxially with the electrode (3) of the sparking plug and integrated with a sparking plug bottom (11). The mass electrode (10) is homogeneous with a sparking plug's housing (2) or is a separate element (15) combined on a permanent basis with the housing (2) of the sparking plug. According to this variant the streaming sparking plug has been designed so that the initiation of the ignition inside the cylinder (17) of the sparking plug takes place in the central part of the cylinder (17) of the sparking plug, whilst the streaming holes (5) are positioned so that the flame that spreads inside the cylinder (17) of the sparking plug covers relatively as short distance as possible from the outbreak of the ignition to the streaming holes (5). In addition to that, to shorten the time the flame reaches the streaming holes £5) and thus hasten the moment of initiation of ejecting hot streams into the combustion chamber of the engine, a flange (12) inside the sparking plug has been used, which can occur in two variants, i.e. as a single part of the housing (2) homogeneous with the housing (2), or as a ring (14) embedded cold in the housing (2) or press assembled inside the housing (2).

Filed: 2013-07-16
Abstract: ﻿The invention belongs to the oil and gas-extraction industry. The joint contains male and female elements with trapezoidal threads with 1:16 taper and contacting each other taper sealing and bearing end surfaces. The slope angle between the thread profile lead-in flank and the thread axis normal line amounts to 10-24, the slope angle between the load flank and the thread axis normal line amounts to -4 to +5. The thread profile crests and lead-in flanks make gaps in between, 0,05-0,15 mm wide, during joint make-up process. The thread profile on the area of mating of the load flank and the crest and on the area of mating of lead-in flank and the crest is produced rounded, with the different rounding radii for the male and female elements. The bearing end surfaces have a 10-20 slope angle with the thread axis normal line. A slope angle between the sealing surface of the male element and the thread axis normal line amounts to 13-18, a slope angle between the sealing surface of the female element and the thread axis normal line amounts to 8-12. On the female element on the thread run-out area and on the area of mating of the sealing and the bearing end surfaces are produced circumferential grooves (12) and (14). The female element area of mating of the sealing surface and the circumferential groove (14) surface and the male element area of mating of the sealing surface and the thread run-out surface are produced rounded. High tightness of the joint under sufficient mechanical loads, its wear resistance during multiple makes and breaks and its operation are achieved.
