摘要： In a liquid-coolant cooling system for an internal combustion engine, of the kind in which a piping by-passing the radiator and put in parallel with respect thereto, is provided, connected by a three-way valve to the radiator inlet piping, the improvement comprising a special throttling valve for the coolant, installed in the radiator-by-passing piping. The special valve allow the rate of flow of liquid through the radiator-by-passing pipe to be increased as the pressure therein is increased. The advantages of the device are to prevent localized overheatings in the engine block and reducing the emission of unburned hydrocarbons when the engine is running cold.

摘要： For an internal combustion engine of the fuel injection type, improved means are disclosed, aiming at reducing the emission of an unburned fraction in the exhaust gases, so as to diminish the causes of pollution of the atmosphere. According to the improvement, fuel feed cut-off means and air feed cut-off means are provided to cut off both the fuel feed and the air feed when the conventional fuel feed regulating means and air throttling means are in ''''idling'''' position and the engine speed is higher than the idling speed.

摘要： The tightness problem in internal combustion engines is usually solved by film between the apical portion of the segments and the chamber walls. The device disclosed herein is controlled by temperature sensitive means, so as to increase the rate of flow of the oil pump when the engine is cold, a condition which is particularly susceptible of causing damages due to cold wear.

摘要： Device for measuring absolute pressures, of the pliable diaphragm type which cooperates with a capsule having rigid walls and containing the diaphragm. In the initial assembly stage, the diaphragm completely mates with the surface of either rigid wall of the capsule, so that virtually no air is sealed therebetween. On completion of the assembly, a preload is imparted to the diaphragm by means of an externally mounted spring, so that a vacuum is created between the diaphragm and the rigid wall confronting the diaphragm with the device being adapted not only to measure absolute pressures, but also to control servo devices in response thereto.
