Threaded retainer

A valve is mounted in a first bore in a first separable section of a transmission to block or allow fluid flow through the first bore to a second bore in a second transmission section depending on whether the first and second sections are joined together or separated. A movable portion of the valve is responsive to an actuator during relative movement of the transmission sections to shift between fluid flow open and fluid flow closed positions. The valve can include a valve housing fixed in the first bore and a carrying plunger biased to the fluid blocking position and responsive to the actuator for movement to the fluid flow open position. The valve forms a fluid flow path between the first and second bores across the gap between the facing surfaces of the joined transmission sections.

Transmission anti-leak valve

A check valve includes a modulation and/or anti-oscillation feature which, in one aspect, modulates the position of the check valve ball relative to the valve seat to maintain the ball in a continuous flow position allowing pressurized fluid flow past the ball while preventing contact between the ball and the valve seat. In another aspect, an increased mass is selectively coupled to or forms a part of the movable valve member to dampen oscillations of the movable valve member in an open fluid flow position without contact with the valve seat.

Check valve with modulation and/or anti-oscillation feature

A cooler bypass apparatus housing has a first fluid passageway connecting a first inlet and a first outlet port, and a second fluid passageway connecting a second inlet port and outlet port. A transverse passageway extends between the first and second fluid passageway. A first valve is disposed in the transverse passageway for one-way fluid flow from the first to the second passageway. A second valve and a thermal actuator coupled to the second valve are disposed in the second passageway. The thermal actuator moves the second valve to fluid flow blocking or fluid flow allowing positions dependent upon fluid temperature.

Cooler bypass assembly

A fluid coupling assembly which has a novel female subassembly capable of receiving a male portion, the female subassembly being formed by spin welding two generally cylindrical plastic parts together, one of the parts being a quick connect end portion and the other part being the barb end portion. The female subassembly is provided with a key or keyway to prevent rotation, to mate with a corresponding key or keyway on the male portion to prevent false connections, and to act as a clear visual aid for orientation. In this design differing barb end portions can be secured to a common quick connect end portion.

The invention is directed to an improved disconnect tool (15). In the preferred embodiment, the disconnect tool is comprised of a first member (16) and a second member (18) connected by a pivot pin (19). The tool includes an engagement means (23) and an expansion means (22) to facilitate the engagement and expansion of a retaining clip so as to permit insertion and removal of a fluid line (39) from a fluid coupling assembly (41). In the preferred embodiment, the expansion means takes the form of a castellated tube portion with a plurality of fingers (20) defining a plurality of grooves (21) therebetween. The fingers are used expand the retaining clip radially and outwardly so as to permit the fluid line to be removed from the fluid coupling assembly. In addition, the present invention is also directed to a method for removing a fluid line from a fluid coupling assembly through the use of a disconnect tool.

A fluid coupling for connecting a fluid line to a threaded port. The coupling includes a male member having a free end, a shoulder portion, and a tapered portion between the free end and the shoulder portion. The female member is provided with an enlarged portion, a groove in a reduced diameter portion which is disposed on the male coupling side of the female coupling, and a threaded end portion on the other side. The female member also has a bore having an enlarged portion and a reduced diameter portion, the reduced diameter portion in turn receiving an O-ring. Slots are provided in the female member between the spring clip groove and the enlarged portion for the reception of a spring clip. The parts are so dimensioned that the O-ring will be contacted about its entire periphery during insertion of the male member into the female member to prevent damage to the male member, the spring clip engaging the shoulder portion of the male member to hold the parts together in their sealing relationship when the male member has been fully inserted.
