Abstract: A pump is disclosed. The pump may have a housing connectable to a transmission of a machine adjacent a front end of the pump. The pump may also have a flange attached to the housing adjacent a rear end of the pump. The flange may have a longitudinal axis extending along a length of the flange, and a transverse axis extending along a width of the flange. The flange may also have a first mounting hole configured to connect an auxiliary pump to the flange. Further, the flange may have a second mounting hole configured to connect a bracket to the flange. The first mounting hole may be positioned on a first axis inclined at an acute angle relative to the longitudinal axis of the flange.

Abstract: A hydraulic fluid supply portion of a hydraulic steering control system may include an accumulator holding a quantity of pressurized steering fluid, and a priority valve. The priority valve may have a priority supply inlet port fluidly connected to the accumulator for receiving pressurized steering fluid from the accumulator, and a priority supply outlet port fluidly connected to a steering flow amplifier circuit. The priority valve may have a normally open position with a minimal pressure drop between the priority supply inlet port and the priority supply outlet port, and a flow restriction position where fluid flow between the ports is restricted. A load signal line from a steering control circuit to the priority valve may bias the priority valve toward the normally open position in response to an operator steering command to provide pressurized steering fluid to the steering flow amplifier circuit.

Abstract translation: 液压转向控制系统的液压流体供应部分可以包括保持一定数量的加压转向流体的蓄能器和优先阀。 优先阀可以具有流体地连接到蓄能器的优先供应入口端口，用于从蓄能器接收加压的转向流体，以及流体地连接到转向流量放大器电路的优先供应出口端口。 优先阀可以具有在优先供应入口和优先供应出口之间具有最小压力降的常开位置，以及限制端口之间的流体流动的流量限制位置。 从转向控制电路到优先阀的负载信号线可以响应于操作者转向命令将优先阀偏压到常开位置，以将加压的转向流体提供给转向流量放大器电路。
