Abstract: A fabricated ball valve is positioned between the inlet and the outlet of a valve housing and includes a first tubular member having sealing faces on each end for seating on valve seats and providing flow therethrough when the first tubular member is aligned between the inlet and the outlet. Second and third tubular axially aligned members have one end connected to the outside of the first member and have sealing faces on their other ends for seating on the valve seats. The second and third members block flow through the valve when the second and third members are aligned between the inlet and outlet. Sealing means may be on either the valve seats or on the movable seat ring connected to each of the other ends of the second and third tubular members.
Abstract: A pressure relief valve to control the opening of a port between two pressure vessels at a predetermined time to eliminate differential pressure between the vessels. More particularly, the lock-up clutch assembly in a torque converter is actuated due to a pressure differential on the opposite sides of the clutch or piston plate, and the pressure relief valve will open upon deceleration of the vehicle driven by the torque converter to equalize the pressure on the opposite sides of the clutch plate and allow disengagement of the clutch plate from the torque converter housing.
