Abstract
A hydraulic power supply is disclosed. This power supply contains a reservoir, an electric motor, and a variable volume pressure compensated pump. The motor used in the device rotates at a speed which does not exceed 1,200 revolutions per minute and produces from about 3 to about 5 horsepower and a torque of from about 12 to about 30 foot pounds. The ratio of the torque to the horsepower (in foot-pounds per horsepower) does not exceed about 4.0. The hydraulic power supply includes an adaptor for connecting the electric motor and the pump and for suspending the electric motor and the pump away from at least one wall of the reservoir.
Claims12
A hydraulic power supply comprised of a reservoir, an electric motor, and a variable volume pressure compensated pump, wherein:
- (a) said electric motor is comprised of means for rotating an electric motor output shaft at a speed which does not exceed 1,200 revolutions per minute and for producing from about 3 to about 5 horsepower and a torque of from about 12 to about 30 foot pounds, provided that the ratio of said torque to said horsepower (in foot-pounds per horsepower) does not exceed about 4.0;
- (b) said reservoir is comprised of a multiplicity of walls;
- (c) said hydraulic power supply is comprised of means for connecting said electric motor and said variable volume pressure compensated pump and for suspending said electric motor and said variable volume pressure compensated pump away from at least one of said walls of said reservoir, wherein:
- 1. said means for connecting and means for suspending is comprised of an adaptor;
- and
- 2. said adaptor is connected to a frame which, in turn, is connected to a multiplicity of vibration isolation mounting devices;
- and
- 3. said vibration isolation mounting devices are connected to one of the walls of said reservoir.
