A fluid system for a pump circuit (10), in particular a hydraulic high-pressure pump circuit, has a function block (12). In the housing of the function block, fluid-conducting paths extend and are connected to valve components (32, 46) at least partially. A filter device is an at least partially integrated constituent part of the function block of the fluid system. The filter device (46) with its filter housing (56) can be connected to the function block (12) such that at least one filter element (70) is received in the installation space (72) of the function block.
