摘要： A gas detector having an intake to let in the gas to be detected and detecting the gas let in through the intake by a gas sensor, in which a porous film is horizontally arranged over the gas intake, in order to prevent the gas permeability of the porous film from being affected by water, oil and/or dust riding on the porous film, wherein a water-repellant and oil-repellant porous film is horizontally provided in a stretched state over the upper end of the intake, and the outside of the outer circumferential edge of the porous film is so structured as to allow liquid on the porous film to fall externally.

摘要： The IC engine nozzle (18) injects fuel in column formation, and its fuel atomiser (30) has a column-shaped fuel channel (32) which is connected to the nozzle itself. A number of atomiser holes (36) are branched by the column-shaped fuel channel (32). Several air inlet channels (38) are provided, one of which is connected to an atomiser hole (36) to blow in air. The bisecting angle between each air inlet channel and the corresp. atomiser hole is set at approx. 90 deg. An air adapter (40) encloses the fuel atomiser (30) so that an airtight air chamber (46) is formed between them. This chamber is connected to the air input channel (38) and an air induction tube (48) induces air from an inlet channel above a throttle valve into the air chamber (46). USE/ADVANTAGE - To inject fuel into an IC engine and achieve efficient atomisation.

摘要： The fuel injector has a valve (12) actuated by a tubular solenoid spool (6). It has a core (3) which extends through the inner part of the spool and an outer section (7) defining an outer magnetic path around the spool. The core can have an outwardly extending flange (3a) on an axially extending part of the core. The outer section can have a disc shaped end plate (7b) in the centre of which is an aperture (8) for the reception of the core without forming a gap between the end plate and the core.

摘要： A fuel injector including a valve housing having a nozzle for columnarly injecting fuel and a valve seat continuing from the nozzle; a valve body reciprocatably mounted in the valve housing and having a valve portion adapted to abut against and retract from the valve seat and thereby close and open the nozzle, respectively; and an adapter fixed to a front end of the valve housing. The adapter is formed with an atomizer hole communicating with the nozzle and an assist air passage extending through a side wall of the adapter for supplying an assist air into the atomizer hole to atomize the columnar fuel injected from the nozzle. Both the valve portion and the valve seat are formed to have surfaces in a conical shape so that upon retraction of the valve portion, the space generated between the surfaces becomes uniform over substantially the length of the surfaces.

摘要： The invention describes a solenoid fuel injector with a valve body which comprises a spherical valve element and a hollow cylindrical sliding element, which is slidably accommodated in a guide bore and the inside of which serves as fuel feed. The sliding element is equipped with openings for the passage of the liquid fuel to its peripheral wall. A peripheral play in the order of 4 to 30 mu is provided between the outer surface of the sliding element and the inner surface of the guide bore. At least the valve element or the sliding element of the valve body is composed of titanium, a titanium alloy, ceramic or ferromagnetic material. In this embodiment the sliding element can be manufactured without a high degree of accuracy and the mass of the valve body can be reduced, resulting in an increase in the response characteristic of the valve body when switching an exciter coil on and off.
