Title: Liquid-operated pumping plant
Inventor: TRINTIGNAC CHRISTIAN
IPC: F04C15/00
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To reduce the frequency due to the noise, which is generated by the operation of a pump during the flowing of the operating liquid through an attenuating chamber, by forming the attenuating chamber, in which the operating liquid discharged from the hydraulic pump is circulated, in a side surface to be closed by a plate of a pump main body. SOLUTION: The operating liquid from a tank 2 is drawn into a drawing chamber through a conduit. When a driving motor 1 is driven, an input shaft 4 is rotated so as to rotate interlocked gears 6, 7, and the operating liquid is pressurized in the condition that it is sealed by the interlocked gears 6, 7.
