Title: Throttle pintle nozzle for fuel injection on an internal combustion engine into a secondary combustion chamber connected by at least one injection duct to a main combustion chamber
Inventor: HAPPEL ROBERT
IPC: F02M61/16
Filed: 1982-09-14
Granted: 1983-12-22
Abstract: In the case of a throttle pintle nozzle for internal combustion engines with fuel injection into a secondary combustion chamber, in addition to a nozzle needle opening against the direction of flow of the fuel, and whose restricting pintle lies in an injection hole of the nozzle body when the nozzle needle is in the closed position and together with this forms a throttle gap, a scavenging valve is arranged in a scavenging duct which connects an annular chamber lying between the injection hole and the needle seat of the nozzle needle to the main combustion chamber avoiding the secondary combustion chamber. During the injection process the scavenging valve is closed, but between each injection process it is opened by the pressures acting on the scavenging valve against the action of a spring. Due to the pulsation of gas fractions in the scavenging duct occurring between the injection processes, a cleaning effect is produced on the injection nozzle by means of which the formation of carbon residues is prevented.

Patent DE-3904774-C1 (DE)
IPC: F26B13/20
Filed: 1989-02-17
Granted: 1990-05-17
Abstract: The invention relates to an apparatus for the floatable guiding of webs of material by air blown against the web. The apparatus comprises blowing boxes 2-6 disposed offset in relation to one another above and below the web 1 of material. Each blowing box 2-6 has two opposite rows of blowing apertures 21 whose blowing direction encloses an acute angle a2 with a deflecting surface 25, 26 which adjoins the edge of the blowing aperture 21 remote from the web 1 of material. The deflecting surface 25 also encloses an acute angle a3 with the web 1 of material. The two acute angles a2, a3 are so selected that the air blown out of the blowing apertures 21 is guided away the deflecting surfaces 25 and against the web 1 of material, where it spreads out in the form of a source flow 30. In this way both a strong air cushion supporting the web 1 of the material is obtained and also a high heat transfer at the web 1 of material and a clearly-defined flow of the blown air from the air cushion.
