Title: Sealing method of cooled type exhaust valve seat of internal-combustion engine
Inventor: MURAKAMI HIROYUKI
IPC: F01L3/22
Filed: 1983-04-20
Abstract: PURPOSE:To intend for simplified construction and reduced price by fixing the valve seat rest of a cylinder head to a cooled-type exhaust valve seat and performing impregnation using impregnant including cavity filler, thereby ensuring tightness to water between the valve seat and the cylinder head. CONSTITUTION:A valve seat 4 is fixed to a valve seat bed 5 sited on the side of a cylinder head 1 by the press-bit or the cold fit method. An annular cooling water passage 6 is formed between the external peripheral face of the valve seat 4 and the rest 5. The passage 6 is connected via a cooling water inlet opening 7 to a cooling water communication opening 8, which is cmmunicated to the water reservoir 10 inside the cylinder head 1 via a cooling water outlet opening 9. For the purpose of ensuring water tightness between the contact faces of the valve seat 4 and the valve seat rest 5, impregnation is performed using impregnant including cavity filler. Consequently, since an O-ring will be unnecessary, simplification of the construction, reduction in price and other advantages may be effected.

Abstract: PURPOSE: To manufacture a nonrefined high tensile steel having high strength and enabling an alloy saving by treating steel contg. a prescribed percentage each of C, Si and Mn as basic components while suitably combining the conditions of heating and rolling with those of accelerated cooling after the rolling.  
     CONSTITUTION: Steel is prepared contg. 0.13W0.30% C, 0.25W0.60% Si and 0.50W2.20% Mn as basic components or further contg. ≥1 kind among Cu, Ni, Cr,  etc. The steel is heated to the Ac 3  point or above and subjected to controlled rolling  making the grains fine, especially rolling in a temp. zone under the recrystallization temp. to form unrecrystallized austenite grains. Before the unrecrystallized austenite recrystallizes, the steel is acceleratedly cooled at 1W60, especially 5W30°C/sec cooling rate without delay. Simultaneously with the accelerated cooling, dehydrogenation is effected by vacuum degassing or other method so as to control hydrogen Hc in the steel at the central part in the plate thickness direction to Hc(ppm) ≤1.10- 0.005σy. Thus, the desired nonrefined high tensile steel is manufactured.

Abstract: PURPOSE:To prevent occurrence of cabitation and hinder the oil hydraulic system from hunting or reverse rotation by furnishing a check valve, by-pass, etc. at the end of a spool valve and by setting the spool valve counter-balanced. CONSTITUTION:Connection of the port 112A on the oil pressure source side with the pump will allow supply of pressure oil to the port 112A on the oil pressure source. As a result, a check valve 118A is opened and pressure oil is supplied to the port 113A on the actuator side through oil lines 117A, 116A. At the same time, the pressure oil in the port 112A on oil pressure source side is supplied also to the oil line 115A, and action of this pressure oil on the check valve 123A through oil lines 127A, 128A will permit the check valve 123A to open. This is further sent to the pilot chamber 120A through oil line 129A and shifts the spool 114 rightwise. Because the oil line 115A is in communication with a by-pass 125A through an orifice 130A, the pressure oil flows into the pilot chamber 120A also from the by-pass 125A, and the spool 114 shifts leftwise.
