First Claim
Patent Images
1. A valve assembly 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 valve assembly;
to establish fluid communication between the inlet/outlet port and the machine fluid reservoir port upon application of negative pressure at the inlet/outlet port, andto establish fluid communication between the inlet/outlet port and the filter port upon application of positive pressure at the inlet/outlet port.
