In recent years, increasingly stringent emission regulations have spurred an electrification
trend in off-highway vehicle technology. To address challenges such as the high cost of …

This paper presents an innovative design of an integrated electro-hydraulic (EH) flow
generation unit able to operate in multiple quadrants. The proposed unit is composed of a …

In this paper, an innovative solution to minimize noise emission, acting on the flow ripple, in
a prototype External Gear Pump (EGP) is presented. Firstly, a new tool capable to …

External gear pumps are among the most popular fluid power positive displacement pumps,
however they often suffer of excessive flow pulsation transmitted to the downstream circuit …

Large flow ripples restrict the development and application of high-order elliptical gear
pumps badly. A new approach is proposed to reduce the flow fluctuations effectively by …

This paper presents a strongly coupled simulation model, Multics HYGESim, for the
displacing action of external gear machines coupled with a detailed simulation of the main …

External gear pumps are one of the most commonly used types of positive displacement
machines in high pressure hydraulic control systems, fuel-injection and fuel transport …

Abstract In this paper, External Gear Machine (EGM) torque losses arising from friction at
lubricating interfaces are modeled by considering mixed lubrication conditions. A novel …

The history of gears with asymmetric teeth is not sufficiently recorded in modern gear
literature, with some gear researchers concluding that asymmetric tooth gears were …

This paper presents a multi-domain dynamic simulation model for continuous-contact helical
gear pumps, which is an unconventional hydraulic pump design that is capable of canceling …
