A service module 44 for a hydraulic fluid system e.g. for regenerative vehicle drive system,, which includes a hydraulic fluid reservoir comprises an outer casing 46 defining an enclosure including an air chamber 54 in fluid communication with ambient air. The service module houses one or more fluid pressure accumulators 48 within the enclosure and a heat exchanger 64 plus motor driven fans 66, 69 is provided for cooling the hydraulic fluid. A valve manifold 74 having a solenoid operated valve connects at least the accumulator and the reservoir under the control of an electronic control unit 80 that receives signals from accumulator pressure sensors 90. |
