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.
