Title: Fuel flow control device for the idling system of a carburettor
IPC: F02M3/09
Filed: 1976-09-03
Abstract: The fuel flow control device is screwed in the tapped hole (3) of the carburettor (4) for the idling nozzle. A fuel line (20) connects the carburettor float housing to the tapped hole (3). In addition a vacuum line (21) is arranged between the carburation chamber and the fuel-air mixture inlet of the engine. The device has a closing body (17) movable in a chamber between two valve seats (8, 12), the actuating means (25) of which body are designed in such a way that when the engine is idling none of the valve seats (8, 12) is closed and that the first of the valve seats is closed at increased engine speed when the carburettor valve flap (23) is opened, whilst the closing body (17) rests on the second valve seat (12) when the engine speed is reduced due to sudden closure of the carburettor valve flap (23). Due to the fact that the full quantity of fuel can flow to the engine by way of an orifice (9) only when idling and the flow is interrupted or reduced in the case of a high or suddenly reduced speed, the fuel consumption can be reduced and combustion conditions improved.

Patent ES-452658-A1 (ES)
Title: Ignition method and apparatus for internal combustion engine
IPC: F02B1/04
Filed: 1976-10-22
Abstract: An internal combustion engine ignition apparatus includes a secondary spark plug having a center electrode to which a high voltage is applied. A cylindrical peripheral electrode surrounds the center electrode and has peripheral openings. Upon the formation of a corona discharge due to the high voltage applied to the center electrode, a strong ionic wind and convection of an air-fuel mixture are produced. The ionic wind causes fuel constituents to be gathered in the vicinity of the peripheral electrode thus preventing production of hydrocarbons due to cooling or quenching of the fuel on the combustion chamber wall. Initial ignition of the air-fuel mixture is by means of a main spark plug. The resultant flames are propagated to the corona discharge portion of the secondary spark plug. The corona discharge is then changed to secondary continuous spark discharge, to thereby positively fire the stratified air-fuel mixture. In another embodiment of the invention the auxiliary combustion chamber has a generally spherical configuration. The spherical auxiliary combustion chamber wall directs the extremely lean air-fuel mixture along a relatively long arcuate path back to outer side areas of the entrance to the auxiliary combustion chamber. The flow out of the auxiliary combustion chamber of the extremely lean air-fuel mixture from which fuel particles have been electrostatically precipitated, is further promoted by forming secondary openings in the wall of the auxiliary combustion chamber. The flow of the very lean air-fuel mixture to either the main or secondary openings in the wall of the auxiliary combustion chamber may be still further promoted by forming arcuate grooves on the inside of the auxiliary combustion chamber wall. The establishment of a corona discharge in either a main or auxiliary combustion chamber is promoted by forming a central electrode with a plurality of projections which extend toward a peripheral electrode which circumscribes the central electrode.

Patent ES-468679-A1 (ES)
Title: Power steering valve system
IPC: B62D5/08
Filed: 1978-04-10
Abstract: A power steering valve system includes an input shaft and an output shaft which are aligned on a common axis, and also includes a control valve mechanism which is located offset from the axis in order to reduce the overall length of the valve system. The control valve mechanism includes a spool valve, a displacement of which from its neutral position controls the flow of a hydraulic oil from an oil pump to or from a power cylinder to assist in directing the steerable road wheels in a given direction. The input and output shafts are operatively associated with a motion translating mechanism which translates the magnitude of a relative torsion between the two shafts into a linear displacement. The motion translating mechanism is operatively associated with the spool valve to displace it from the neutral position in accordance with the magnitude of relative torsion between the two shafts.
