摘要： The spark advance control apparatus of the invention comprises a vacuum advance control mechanism and a speed advance control circuit. The vacuum advance control mechanism senses the vacuum pressure in the intake manifold of an internal combustion engine and generates an electrical pulse in advanced timing in relation to the sensed vacuum. The speed advance control circuit receives the pulse from the vacuum advance control mechanism, converts it into a voltage signal representative of the revolution of the engine crankshaft and generates an output voltage which varies nonlinearly as a function of the voltage signal. A pulse-width generator is provided having a first input connected to receive the pulse from the vacuum advance control mechanism and a second input connected to receive the nonlinear speed related voltage signal to generate a pulse which commences in response to the vacuum advance pulse and ends at a time determined by the speed related voltage signal. The trailing edge of the output from the pulse-width converter is utilized for ignition.

摘要： A pneumatic pressure responsive valve assembly for a pneumatic control system in a vehicle includes a power piston movable due to the pneumatic pressure difference between atmospheric pressure and a signaling vacuum pressure, which piston comprises a valve member cooperable with a valve seat. The valve member is slidably mounted with respect to the power piston. A weak spring disposed between the valve member and the power piston normally seats the valve member on the valve seat and movement of the power piston will unseat the valve member to provide a pneumatic control function.

摘要： An ignition timing change-over device for an internal combustion engine comprising a vacuum advancer for causing rotation of the breaker plate of the contact breaker toward an ignition timing advancing direction, a vacuum retarder for causing rotation of the breaker plate toward an ignition timing retarding direction, a first valve unit connected to the vacuum advancer and vacuum retarder, and a second valve unit connected to the vacuum retarder and the first valve unit. The first valve unit is used for supplying the suction vacuum into the vacuum advancer when the temperature of the engine is lower than a predetermined value, supplying the suction vacuum into the vacuum retarder when the engine temperature is higher than the predetermined value, and supplying the suction vacuum into the vacuum advancer when the engine temperature is higher than the predetermined value and the vacuum in the intake manifold is higher than a predetermined value, while the second valve unit acts to permit communication between the vacuum retarder and the atmosphere when the vacuum in the intake manifold is higher than the predetermined value and to permit communication between the vacuum retarder and the first valve unit when the vacuum in the intake manifold is lower than the predetermined value, so that the ignition timing can be changed depending on variations of the two variables, that is, the engine temperature and the intake manifold vacuum.

摘要： A vacuum relay valve for isolating a vacuum operated dependent device from a contaminated vacuum signal source includes a check valve and an atmospheric bleed valve arranged such that a negative-going pressure change in the vacuum source causes the check valve to open and the bleed valve to close, permitting evacuation of the vacuum operated device by flow toward the source, while a positive-going pressure change in the vacuum source causes the check valve to close and the bleed valve to open thereby isolating the vacuum operated device from the signal source and permitting the pressure in the device to rise by infusion of atmospheric air. The relay valve may include a timing restriction arranged for isolation from the signal source, which is purged by unidirectional flow each time the device is evacuated.

摘要： An altitude compensated vacuum control system for regulating the vacuum servo mechanism of an internal combustion engine of the type having a distributor with a vacuum servo controlled advance mechanism incorporating a positive stop for maximum spark advance, a carburetor to provide a source of vacuum to operate said vacuum servo mechanism and a vacuum control valve assembly for regulating the vacuum servo mechanism of said distributor. The vacuum control valve assembly receives a spark port vacuum signal from the carburetor to maintain a predetermined vacuum spark advance as the engine begins to accelerate. Upon attaining the predetermined vacuum spark advance and at a given speed, the control assembly becomes operative to sum the initial first predetermined level vacuum signal to a secondary altitude compensated vacuum source signal, which is a function of an engine operating parameter, thereby causing the vacuum servo spark advance mechanism in the distributor to obtain a maximum spark advance by moving to a positive stop within the distributor. This full vacuum advance is maintained independent of the degradation of the vacuum signals as a result of changes in altitude, provided the spark port signal is greater than the full vacuum spark advance signal.
