1. A valve assembly comprising:

  • a housing comprising;

    an inlet/outlet port structured for fluid communication with at least one fluid component external to the valve assembly;

    a machine fluid reservoir port structured for fluid communication with at least one fluid reservoir of a machine;

    a filter port structured for fluid communication with at least one filter of the machine; and

    ,an actuating mechanism operably positioned and structured within the housing; and

    wherein the actuating valve mechanism comprises an open position and a closed position, wherein, upon application of negative pressure at the inlet/outlet port, the actuating mechanism is in the open position and the actuating mechanism is configured to establish a first channel within the housing for fluid communication between the inlet/outlet port and the machine fluid reservoir port; and

    wherein, upon application of positive pressure at the inlet/outlet port, the actuating mechanism is in the closed position and the actuating mechanism is configured to establish a second channel within the housing for fluid communication between the inlet/outlet port and the filter port.
