摘要： A vertically oriented hydraulic power unit (40) for an elevator drive includes an outer tank (50) for drive fluid and an inner tank (88) for fluid used to submerge and cool a motor, the fluids being exchangeable to maintain temperature in the inner tank (88) at or below a specified maximum temperature. Oil returning from an elevator piston is fed into said inner tank (88) to keep the inner tank (88) sufficiently cool.

摘要： A hydraulic elevator includes a car (14) engaged with a first hydraulic ram (16), a counterweight (18) engaged with a second hydraulic ram (20), and a pump (28) to transfer hydraulic fluid between the hydraulic rams. The counterweight hydraulically balances the car without the requirement of a roped connection between the car and counterweight. A fluid flow system (22) controls the transfer of hydraulic fluid between the hydraulic rams. As a result, there is no tank or reservoir for hydraulic fluid.
