Abstract:
A throttle body (1) which has a throttle housing (2) made of plastic, a throttle butterfly (5) being pivotably mounted in a conduit section (3) of the throttle housing (2), wherein, a metal cylinder (12) is provided in the conduit section (3) over at least part of the pivoting range of the throttle butterfly (5).
Abstract:
A housing (1) for a load adjusting device of an actuating drive for a throttle of an internal combustion engine, the housing having two housing parts (2, 3), has a circumferential sheet-metal strip (10). The sheet-metal strip (10) in each case engages behind an edge (8, 9) of the housing parts (2, 3). The housing parts (2, 3) are therefore prestressed uniformly against each other and reliably sealed off against each other.
Abstract:
Limit regulation system for a pressurized water nuclear reactor in combination with a steam generating system connected to a turbine, the nuclear reactor having control rods as well as an operational regulation system and a protective system, includes reactor power limiting means operatively associated with the control rods for positioning the same and having response values between operating ranges of the operational regulation system, on the one hand, and response values of the protective system, on the other hand, and a live steam-minimal pressure regulation system cooperating with the reactor power limiting means and operatively connected to a steam inlet valve to the turbine for controlling the same.
Abstract:
A pressurized-water reactor with a core height of at least 3.5 m, is operated by using at least 50 measuring probes which are distributed throughout the core and which feed into a computer. The latter computes in advance a program of operation, by which individual control rods are adjusted, regardless of load changes, over the height of the core in such a manner that local power peaks are avoided.
