Abstract

A head for closing a nuclear reactor pressure vessel shell includes an arcuate dome having an integral head flange which includes a mating surface for sealingly mating with the shell upon assembly therewith. The head flange includes an internal passage extending therethrough with a first port being disposed on the head mating surface. A vent line includes a proximal end disposed in flow communication with the head internal passage, and a distal end disposed in flow communication with the inside of the dome for channeling a fluid therethrough. The vent line is fixedly joined to the dome and is carried therewith when the head is assembled to and disassembled from the shell.

Entake or exhaust valve actuator

Patent Smietana, J M

Intake or exhaust valve actuator assembly is described for an internal combustion engine for hydraulically opening and closing an intake or exhaust valve for admitting intake gases from an intake conduit into a combustion chamber or permitting exhaust gases to escape from the combustion chamber into an exhaust conduit, the engine including a piston which oscillates in the combustion chamber, a cylinder head which encloses the combustion chamber and contains the intake or exhaust valve and the intake or exhaust conduit, and timing means to detect phase of the piston as it oscillates in the combustion chamber; the intake ormore »« less
Foreign object separator for a reactor cooling system

Patent Dillmann, C W

This patent describes a nuclear reactor having an annular vessel sidewall spaced radially outwardly from an annular core shroud around a longitudinal centerline axis to define an annular flow passage for channeling a coolant in a direction parallel to the centerline axis. It comprises a vessel endwall being arcuate in a longitudinal plane from a first portion joined to the vessel sidewall to a second portion spaced radially inwardly from the first portion for turning the coolant; the core shroud including an intermediate portion spaced radially inwardly from the endwall first portion to define an annular inlet for receiving themore »« less
Sealing structure of cylinder head cover

Patent Mikio, N

This patent describes a structure for mounting a cylinder head cover on a cylinder head of an internal combustion engine. The cylinder head has plug holes for mounting ignition plugs therethrough, a plug tube fixedly inserted into each of the plug holes and protruding upward from the cylinder head, the cylinder head cover being mounted on the cylinder head via a sealing gasket arranged therealong. The mounting structure comprises: the cylinder head cover having plug mounting holes, each of which is formed in substantially reversed-conical surface having a diameter that becomes gradually smaller toward the lower portion thereof. The plugmore »« less
