Abstract: A series hydrostatic transmission for a vehicle having a wheel where the transmission comprises a hydraulic pump and a hydraulic motor each having a pumping mode and motoring mode. The pump and motor each have cylinders of cyclically varying working volume in which hydraulic fluid displacement through each cylinder is regulated and in phased relationship to cycles of cylinder working volume with reference to a phase signal. The transmission has a first mode in which the pump and motor are fluidly connected to each other, a second mode in which energy from hydraulic fluid pressurised by the motor in the pumping mode is transferred to an energy store, and a third mode in which energy from the energy store drives the motor, and wherein the motor comprises a valve assembly disposed between a high pressure line and a working chamber of the motor.

Abstract: A hydraulic apparatus including an electronically commutated machine having a plurality of working chambers which are controlled on each cycle of working chamber volume to carry out active or inactive cycles of working chamber volume allows only a plurality of defined fractions of cycles to be active cycles to avoid generating frequencies of active cycles which cause low frequency resonances. The demand signal may be quantised into fractions m/n where n is an integer below a threshold selected to avoid repeating patterns of active cycles of more than a cut-off length.

Abstract: A valve unit for regulating the flow of working fluid between a working chamber of a fluid working machine and both a first working fluid line and second working fluid line, the valve unit comprising: a first valve comprising a first valve member and one or more cooperating first valve seats, a second valve comprising a second valve member and one or more cooperating second valve seats, an actuator coupled to both the first and second valve members through which a force may be applied to urge the first valve member open or closed and to urge the second valve member open or closed, a coupling between the actuator and the first valve member, wherein the coupling between the actuator and the first valve member comprises a connector which extends at least partially through the second valve member.
