Abstract
A power pack unit includes a first hydraulic pump including a first pump enclosure accommodating a first pump cartridge. A second hydraulic pump includes a second pump enclosure accommodating a second pump cartridge. A hydraulic fluid reservoir is positioned between the first and second hydraulic pumps. A first end of the reservoir is secured to the first pump enclosure and a second end of the reservoir is secured to the second pump enclosure. The first and second hydraulic pumps and the reservoir can extend along a common axis. First and second motors can be connected to the first and second pumps. The entire structure can extend along a common axis.
Claims11
A power pack unit comprising:
- a first hydraulic pump;
- a first motor which mechanically drives said first hydraulic pump;
- a second hydraulic pump;
- a second motor which mechanically drives said second hydraulic pump;
- a hydraulic fluid reservoir defined within a hydraulic fluid reservoir housing, the hydraulic fluid reservoir housing being positioned between and adjacent to the first and second hydraulic pumps, the hydraulic fluid reservoir fluidly communicating with the first and second hydraulic pumps;
- the first and second hydraulic pumps, the hydraulic fluid reservoir housing, and the first and second motors being arranged to extend along a common axis;
- the first and second hydraulic pumps being exterior to the hydraulic fluid reservoir thereby establishing a distance between the first and second hydraulic pumps measured along the common axis through the hydraulic fluid reservoir;
- and,
- a suction tube for supplying hydraulic fluid to the first hydraulic pump, the suction tube extending into the hydraulic fluid reservoir from the first hydraulic pump toward the second hydraulic pump a distance at least 50% of the established distance between first and second hydraulic pumps.
