Title: Internal combustion engine tappet
Inventor: KANZAKI TATSUO
IPC: F01L1/20
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To enhance the joining strength of a cam receiving plate by forming an air escaping slit opening at its outer end in the outer peripheral face of a tappet body on the top face of a tappet main body top face in a matter formed by joining the cam receiving plate to the top face of the tappet body top wall through projection welding. SOLUTION: A tappet body 1 with its top face blocked by a top wall 1a is made of aluminum alloy, and a cam receiving plate 2 having formed small protrusions 3 on the circumference of its bottom face is joined to the top face of the top wall 1a by projection welding. Four air escaping slits 4 opening at the outer ends thereof in the outer peripheral face of the tappet body 1 are formed at equal intervals directing in the radiation direction on the top face of the top wall 1a. The air escaping slits 4 are formed into such a length as the inner ends 4a thereof sufficiently reach an inner area exceeding the small protrusions 3. Thereby, at an projection welding time, no air of the inner area surrounded by the small protrusions 3a is allowed to be trapped so as to enhance the joining strength of the cam receiving plate 2.

Abstract: PURPOSE: To produce steam usable for, for example, power generation, etc., by taking out geothermal brine from an underground aquifer and, after separating non-condensable gases from the brine, flashing the brine. CONSTITUTION: Geothermal brine containing water, non-condensable gases, and toxic elements is taken out from a well drilled into an underground aquifer and brine containing no condensable gas is produced by separating the non- condensable gases from the brine.

Then, steam and air-free flashed brine are produced by flashing the brine containing no non- condensable gas and the flashed brine is prevented from coming into contact with the air by establishing an air-free flashed brine handling system. The flashed brine is divided into sludge and clear brine and the clear brine is reinjected into the underground aquifer. Non-toxic solid materials are produced from the sludge by removing the dissolved toxic elements by cleaning the sludge.
