摘要：
The invention concerns an external gear hydraulic pump including a pump body housing rotating pinions that mutually engage. Located on opposite sides of the body are a cover and a support, forming an outlet manifold for high pressure fluid. Acoustic insulation elements damp the vibrations produced by the pinions. The acoustic insulation elements acoustically decouple the pump body from the support.
