A hydrodynamic retarder system for a vehicle is provided. The hydrodynamic retarder system comprises a fluid sump for housing a fluid and having a first fluid volume; a pump for pumping a fluid from the fluid sump; a retarder having a fluid chamber for housing a second volume of the fluid; a second sump for housing at least a third volume of the fluid and fluidly connected to the fluid sump; the third volume being substantially the same volume as the second volume; and a retarder inlet valve fluidly connected to the fluid sump via the pump and movable between a closed position for directing fluid flow to the second sump and an open position for directing fluid flow to the retarder, the valve movable from the closed position to the open position when the retarder is activated. In a first operational state with the vehicle powered on and the retarder deactivated, the pump directs fluid flow from fluid sump to the retarder inlet valve being in the closed position and directing fluid flowto second sump. In a second operational state with the vehicle on and retarder activated, the retarder inlet valve moves to the open position directing fluid flow into the retarder chamber and flowingout of the retarder chamber after filling the second volume and discharging to the second sump.

    提供了一种用于车辆的液力减速器系统。该液力减速器系统包括流体贮槽,用于容纳流体并具有第一流体体积;泵,用于泵送来自流体贮槽的流体;减速器,具有用于容纳第二体积的流体的流体腔室;第二贮槽,用于容纳至少第三体积的流体并且流体连接到流体贮槽;第三体积与第二体积是基本相同的体积;以及减速器入口阀,经由泵流体连接到流体贮槽,并且能在用于将流体流引导到第二贮槽的闭合位置和用于将流体流引导到减速器的打开位置之间移动,当启动减速器时,阀从闭合位置移动到打开位置。在车辆接通动力且减速器停用的第一操作状态中,泵将流体流从流体贮槽引导到处于闭合位置的减速器入口阀,并将流体流引导到第二贮槽。在车辆开启且减速器启动的第二操作状态中,减速器入口阀移动到打开位置,从而引导流体流入减速器腔室,并在填充第二体积之后从减速器腔室流出并排放到第二贮槽。
