A de-aeration reservoir for a vehicle includes an inlet and an outlet., and a receptacle configured to receive a filter therein, the receptacle downstream from the inlet. The de-aeration reservoir further includes a plurality of chambers formed in the reservoir downstream from the receptacle, and a de-aeration opening formed in the receptacle and fluidly connecting the receptacle to an inlet chamber of the plurality of chambers.

A piston cooling device includes a main body which includes a communication path communicating with an oil passage provided in the internal combustion engine, a nozzle pipe portion which includes an oil injection port for injecting an oil passing through the communication path, toward the piston, and a filter which is provided at an upstream side of the nozzle pipe portion in an oil flow path to filter the oil. The main body includes a cylindrical portion inserted into the oil passage. The filter has a bottomed cylindrical shape in which a filter side surface stands from a filter bottom surface, and is held inside the cylindrical portion. Filter holes are formed in the filter bottom surface and the filter side surface. The filter is disposed such that the filter bottom surface protrudes further upstream side in the oil flow path than a tip end of the cylindrical portion.

A method for replacing a volume of coolant fluid in a circulating system in diesel engine system that includes the steps of establishing pneumatic connection with at least one location in the diesel engine coolant fluid circulating system; establishing fluid connection with at least one point in the diesel engine coolant fluid circulating system, the fluid connection location being different from the pneumatic connection; and after pneumatic and fluid connection is established, drawing a vacuum pressure through said pneumatic connection and introducing the volume of coolant fluid into the through said fluid connection as well as a device for accomplishing the same.

A cooling module for a motor vehicle for cooling at least one drive unit of the motor vehicle, having a cooling module housing which has a coolant reservoir for providing a liquid or gaseous cooling medium; a first interface unit for accommodating a predetermined pump unit; a second interface unit for accommodating a predetermined filter unit; and a third interface unit for accommodating a predetermined heat exchange unit.

A filter housing is provided. The filter housing includes a circumferential rib provided on an outer surface thereof. The filter housing also includes a first longitudinal rib provided on the outer surface thereof. The first longitudinal rib connects and extends away from the circumferential rib along a length of the filter housing. The first longitudinal rib defines a first thickness thereof. The first thickness tapers towards the circumferential rib. The filter housing further includes a second longitudinal rib provided on the outer surface thereof. The second longitudinal rib is provided opposing the first longitudinal rib. The second longitudinal rib connects and extends away from the circumferential rib along the length of the filter housing. The second longitudinal rib defines a second thickness thereof. The second thickness tapers towards the circumferential rib.

A filter element sensor module having a housing, a sidewall of the housing including a recessed portion. The sensor module including a sensor assembly being provided within the housing about a sensor port interface being provided at one end of the housing. The sensor module also including processing circuitry being configured to receive signals from the sensor assembly and communication module, the communication module being configured to transmit one or more sensed parameters from the sensor assembly.

A valve group (10) is housed in a duct (40) of a support body (4) of an oil filtering assembly provided with a valve body (11) fixed to the support body (4). An obturator (15) is fitted in an axially movable manner on the valve body (11) and includes an obturator positioner and mover (18). The obturator (15) is movable by the obturator positioner and mover (18) as a function of the oil temperature values respectively in a first, a second and a third operating configuration, in which the oil is cooled, heated, for example by a heat exchanger, or sent directly to the filtering device. Moreover, the obturator (15) is movable by the obturator positioner and mover (18) as a function of the oil pressure values directly to the filtering device, preventing oil access to the heat exchanger.
