摘要： A hydraulic system for use in an automotive vehicle. A source of hydraulic pressure selectively operates in two modes. In one mode, it feeds a radiator cooling fan and a power steering system in parallel when a system pressure or flow exceeds a predetermined pressure rate. In another mode, it feeds the radiator cooling fan and the power steering system in series when the system pressure or flow is less than the predetermined pressure or flow.

摘要： A pulsation damper and noise attenuator assembly comprising a housing having an inlet port and an outlet port fluidly connecting the interior of the housing to the flow path of the fluid flow system. A base is mounted to the housing and comprises a vent fluidly connecting the interior of the housing to an external fluid source. A sealing member such as an expandable bellows or piston is seated within the housing and creates a fluid tight seal between the fluid flow path and the external fluid source sealing member. The external fluid biases the sealing member in a forward direction. The sealing member acting against the N.sub.2 fluid under pressure absorbs the full force of the hydraulic shock waves or pulsation within a high pressure fluid flow system as the assembly is mounted directly within the flow path of the fluid. The shock wave is exposed across the full face of the sealing member and dampened prior to the fluid continuing along the flow path.

摘要： A hydraulic machine of the gerotor type. The machine uses two gerotors which are preferably coplanar, and positioned nearly concentric to each other. This dual arrangement approximately doubles the displacement of hydraulic fluid per revolution, compared with a single gerotor, and thus doubles power transfer. Yet the housing containing the gerotors need only be large enough to contain the larger gerotor.

摘要： A pulsation damper and noise attenuator assembly comprising a housing having an inlet port and an outlet port fluidly connecting the interior of the housing to the flow path of the fluid flow system. A base is mounted to the housing and comprises a vent fluidly connecting the interior of the housing to the atmosphere. A piston seated within the housing creates a fluid tight seal between the fluid flow path and the vented atmospheric pressure. Belleville springs bias the piston in a forward direction. The piston absorbs the full force of the hydraulic shock waves or pulsation within a high pressure fluid flow system as the assembly is mounted directly within the flow path of the fluid. The shock wave is exposed across the full face of the piston and dampened prior to the fluid continuing along the flow path.
