Title: Steam generator feed-water preheater improvement
IPC: F22B1/02
Filed: 1974-01-24
Abstract: A steam generator includes a feed-water casing having a steam output outlet and enclosing a horizontal tube sheet in which are mounted the ends of a plurality of heat-exchanger tubes extending upwardly therefrom and radially enclosed by a casing of a feed-water preheater having a series of vertically interspaced transverse feed-water flow baffles through which the heat exchanger tubes extend and which define alternately horizontal offset flow passages. A feed-water inlet connects with the upper portion of this series of baffles for downward flow through the preheater of externally introduced feed-water, this flow being deflected transversely alternately in opposite directions or back and forth between the heat-exchanger tubes prior to discharge into the feed-water casing. The feed-water flowing through the preheater may convert to steam which collects beneath one or more of the preheater's flow baffles, reducing the feed-water flow rate and resulting in further and more rapid steam conversion while precipitating compounds inevitably included by the feed-water and which are corrosive with respect to the preheater's parts and the heat exchanger itself. According to the disclosure, steam venting tubes are built into the preheater so as to extend from those areas beneath the flow baffle plates where such steam can collect, and which extend upwardly through the preheater and open above the latter into the feed-water casing where the steam can rise upwardly through ascending feed-water and escape.

Patent ES-466790-A1 (ES)
Title: Fuel injector
IPC: F02M61/20
Filed: 1978-02-08
Abstract: A fuel injector, which is principally for use in a compression ignition engine, comprises a body having a bore therethrough in which a valve member is slidably mounted for co-operation with a seating to contro1 the flow of fuel past the latter, the valve member being biased into engagement with the seating by a compression spring. The biasing force of the spring, and therefore the fuel pressure at which the valve member opens, can be adjusted by rotating a collar relative to the body. The collar is both internally and externally screw-threaded, and engages complementary threading on the interior of the bore. An externally screw-threaded retaining member engages the internal threading on the collar and also has an abutment which engages the body, the retaining member serving to retain the collar in position in the bore. Once the biasing force of the spring has been set by rotating the collar, the retaining member prevents the collar from being inadvertently rotated subsequently.
