A cooling circuit includes vehicle components and a jet manifold. The vehicle components are configured to receive coolant and include a first vehicle component and a second vehicle component. The jet manifold includes a first input, a second input and a nozzle. The first input is configured to receive coolant from the first vehicle component. The second input is configured to receive coolant from the second vehicle component. The nozzle is configured to increase pressure of the coolant received at the first input to generate a jet stream and a low-pressure zone in a cavity of a body of the jet manifold, the low-pressure zone created by the jet stream drawing coolant from the second input.

Vehicle coolant circuits including jet manifolds

A pump includes a first gear plate and a first pair of counter rotating gears positioned on a first side of the gear plate. The pair of counter rotating gears draws fluid from an inlet and transfers the fluid into an outlet of a common manifold. The gear plate has a cutout to increase the flow of fluid into the common manifold.

Scavenge gear plate for improved flow

A gear assembly of a scavenge oil pump for a vehicle is provided. The assembly comprises a first pair of meshing gears comprising a first drive gear disposed about a drive shaft and a first slave gear disposed about a slave drive in parallel relationship with the drive shaft. The first drive gear and first slave gear are in rotational meshing cooperation. The assembly comprises a second pair of meshing gears comprising a second drive gear disposed about the drive shaft and a second slave gear disposed about the slave drive. The second drive gear and second slave gear are in rotational meshing cooperation. The second pair of meshing gears is disposed linearly adjacent to the first pair of meshing gears. The first pair and the second pair of meshing gears have about &#x215c; of a tooth spacing relative to each other for torque transmission of scavenge oil.
