Abstract: An apparatus comprising a synthetically commutated machine with one or more services, a prime mover coupled to the machine, a hydraulic circuit extending between the services and hydraulic loads to fluidically connect the services to the hydraulic loads such that groups of one or more services are fluidically connected to respective groups of one or more hydraulic loads. The apparatus configured such that the flow of hydraulic fluid to or from a group of services of the machine is controlled responsive to measuring a flow rate and/or pressure requirement of the hydraulic loads which are fluidically connected to the services, or receiving a demand signal indicative of a demanded pressure and/or flow rate based on a pressure and/or flow demand of hydraulic loads which are fluidically connected to the services.

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.

Abstract: A rocking cylinder assembly comprising a cylinder, rotatable about a rocking axis between first and second end positions, having a cylinder bore terminating at a cylinder bearing surface and a cylinder aperture, and a bearing component having a component bore terminating at a component bearing surface and a component aperture. The ratio of the area of the second one of the apertures to the square of the maximum extent of the second one of the apertures in a direction perpendicular to the rocking axis and perpendicular to a second axis for fluid flow is greater than the ratio of the area of the first one of the apertures to the square of the maximum extent of the first one of the apertures in a direction perpendicular to the rocking axis and perpendicular to a first axis for fluid flow.

Abstract: A hydraulic apparatus has a plurality of pump modules each of which is formed by a plurality of working chambers having a common high pressure manifold. A connecting circuit switchably connects pump modules to first and second hydraulic circuit portions to allocate capacity as first and second demands for hydraulic fluid vary. In an apparatus which may have two or more connecting circuit outputs, valves may be controlled or working chamber pumping cycles made inactive to facilitate the reallocation of a pump module from one output to another, and a control strategy addresses pump module allocation when the demands for hydraulic fluid exceed available capacity.
