摘要： A method of damping hydraulic pressure waves and of removing peaks from pressure variations in the feed ducts of a hydraulic pump resulting from excess fluid returned with high kinetic energy to a feed chamber uses this kinetic energy directly to increase temporarily the volume of the feed chamber by a value lying in the range 10% to 30% of the maximum cylinder capacity of the hydraulic pump. The pump has a resiliently movable wall disposed in a feed chamber perpendicularly to the direction of a high kinetic energy jet of fluid from a passageway opening into the chamber. The wall is located on the axis of the passageway at a distance from the opening that is not more than 1.5 times the smallest diameter of the passageway. The invention also relates to a hydraulic pump for implementing the method. Applicable to fuel injection pumps in Diesel engines.

摘要： The present invention provides a method of regulating the temperature of the inside surface of cylinder liners in an internal combustion engine (e.g. a diesel engine) which is cooled by a flow of cooling fluid, the method including the improvement whereby the temperature of the cooling fluid is regulated in such a manner as to maintain the temperature of the inside surface of the cylinder liners at a reference temperature, regardless of the engine load. The invention also provides apparatus for performing the above method. The apparatus includes temperature sensors (6) situated in the thickness of the liner (1) walls between the inside surfaces thereof (1') and the cooling fluid flow ducts (10) passing through the wall.

摘要： This invention relates to a method and devices for improving the external cooling of an exhaust valve of internal combustion engines. This method consists in extending the open period of the exhaust valve beyond the normal closing instant by preventing it from closing completely at that instant but by reducing the free flow section between the valve and its seat to a residual value which is substantially constant and small compared to the maximum flow section corresponding to the full opening of the valve. Said devices comprise means for obtaining such residual opening of the exhaust valve.
