Title: Gas burner
Inventor: KOHLMANN HANS-ALBRECHT
IPC: F23D14/70
Filed: 1988-09-22
Abstract: In the case of a gas burner, the burner chamber (1) of which is supplied with a fuel/air mixture, for example via mixing pipes (2), air is situated, in certain regions above a burner-chamber wall (7) penetrated by gas outlet openings (9), at least one radiating body (3) which extends above that region of the burner chamber (1) which encloses a mixing chamber and into which the mixing pipes (2) open. In the case of a burner of circular or polygonal configuration, the radiating body (3) can be offset with respect to the flat upper side of the burner chamber (1). It is also possible for a plurality of radiating bodies (3) to be arranged centrally symmetrically on this upper side. The radiating bodies (3) can also be designed as holding means, running parallel to one another, of plate-like burner-chamber walls (7), the lower regions of the radiating bodies (3) being profiled as holding means, whereas the upper regions project above the burner-chamber walls (7). <IMAGE>

Inventor: MIYAMOTO YASUHIKO
IPC: B60W50/06
Filed: 1988-10-26
Abstract: A throttle valve shaft 13 carries a throttle lever 16 mounted loosely thereon so as to be rotatable independently of the throttle shaft by depression of an accelerator pedal 2. A control arm 14 is fixedly mounted on the throttle shaft 13 and is connected to a lever 11 of a centifugal governor (8a, .....8e, Fig 4) on a gearbox output shaft (4b) through a cable 12. A torsion coil spring 18 has one end engaged with the lever (11) and the other end engaged with the arm 14. Depression of the accelerator pedal 2 causes the throttle lever 16 to rotate, which rotation is transmitted via the coil spring 18 to the control arm 14 which in turn rotates the throttle shaft 13. The operation of the governor causes the control arm 14 to rotate with the coil spring being elastically deformed when a predetermined vehicle speed is exceeded. <IMAGE>
