Patent ID: 7555999

Claim:
A hydraulic circuit including an added motion valve system and a sump including fluid, wherein the fluid is defined by a flow rate, wherein a change in the flow rate is dependent upon a change in viscosity of the fluid, wherein the change in viscosity of the fluid is dependent upon a change in temperature of the fluid, comprising: an added motion valve body defining an actuator volume, wherein the added motion valve body includes a first port, a second port, and a third port, wherein the added motion valve body receives the fluid flowing through a first fluid supply channel that is in fluid communication with the sump, and a second fluid supply channel that is in fluid communication with the sump, wherein the first fluid supply channel is in fluid communication with the first port and the second port, wherein the second fluid supply channel is in fluid communication with the third port; means for selectively permitting movement of the fluid to and from the actuator volume, wherein the means for selectively permitting movement of the fluid to and from the actuator volume includes a first valve that is associated with the first fluid supply channel, wherein the first valve is movable between open and closed positions; and means for compensating for a positive flow rate of the fluid through the first fluid supply channel to the added motion valve body, wherein the means for compensating for the positive flow rate of the fluid through the first fluid supply channel to the added motion valve body includes a second valve associated with the second fluid supply channel, wherein the second valve is movable between open and closed positions, wherein the second valve is open at the same time as the first valve to compensate for the positive flow rate of the fluid through the first fluid supply channel to the added motion valve body.
