Abstract: A hydraulic fan circuit is provided. The hydraulic fan circuit includes a tank, a motor having a fluid inlet and a fluid outlet and a pump to draw fluid at a low pressure from the tank and discharge the fluid at elevated pressures to the motor via the fluid inlet. The hydraulic fan circuit further includes a directional control valve disposed between the fluid outlet of the motor and the tank. The directional control valve is operable to move between a flow blocking position and a flow passing position. Further, the directional control valve is configured to reduce a positive speed of the motor below a lowest positive speed attainable through control of pump output. Furthermore, the hydraulic fan circuit includes a pressure control circuit configured to provide a pilot fluid flow at varying pressure to move the directional control valve.

Abstract: A fluid drain manifold is disclosed. The fluid drain manifold can include a manifold body and a plurality of hollow interior channels extending through an interior of the manifold body between an upper end and a bottom end of the manifold body. The plurality of hollow interior channels can include a plurality of individual drain line channels and an outlet channel. The outlet channel can be disposed within the interior of the manifold body, and the outlet channel can include an upper end and an open lower, outlet end. The open lower outlet end of the outlet channel can be positioned at the bottom end of the manifold body. Each of the plurality of individual drain line channels can include an open upper, inlet end at the upper end of the manifold body and an open lower, outlet end fluidly connected to the outlet channel.
