  • Patent number: 6202982
    Abstract: Members for pushing the tabs of an annular part include radial studs forming cams, there being as many of these as there are catching tabs, the cams having the same distribution as the tabs into the gaps between which they are inserted in the unlocked position, each tab being equipped with a cylindrical or cam-shaped internal bearing surface capable of bearing on one of the studs in order, by reaction, to push its external catching tooth radially outward, the annular part being connected to a turning member which has a restricted angular travel between two positions, namely an unlocked and identified rotational position of the annular part, in which position the tabs are free to flex, and a locked rotational position of the annular part, in which position the tabs are locked and pushed back by their respective studs, and locked under the rolled rim.

  • Patent number: 6167946
    Abstract: A radiator includes a core portion, a header tank, a side plate attached to the core portion and a bracket through which the radiator is mounted to a vehicle. The bracket is separately formed from the header tank, and is connected to the side plate through a bolt. As a result, the radiator is readily mounted to a vehicle of a different model by only changing an attachment position of the bracket to the radiator, without modifying the header tank. Further, the bracket includes a coolant receiving portion disposed to face a drain outlet of the header tank with a predetermined gap therebetween. Therefore, coolant discharged from the header tank collides with the coolant receiving portion to reduce its dynamic pressure. As a result, coolant drained from the radiator is restricted from being scattered.

  • Patent number: 5971357
    Abstract: A fluid delivery valve for use in fluid conducting systems includes a rigid bracing member positioned within a hollow, flexible, resilient valve housing. By applying opposing lateral forces to the external surface of the housing near a widened portion of the bracing member, the valve housing deforms around the widened portion and the valve is actuated. Actuating the valve permits fluid communication between the inner chamber of the valve housing, and a channel which extends through an enlarged portion. The channels are sealed by the inner wall of the housing when the opposing forces are released. The fluid is thus selectively allowed to travel past the bracing member.

  • Patent number: 5647573
    Abstract: To resist mechanical forces tending to unseat a fluid valve applied to seal against a high fluid pressure, a fluid valve assembly is equipped with a valve block that, in response to the high fluid pressure, causes a locking member to be forcibly wedged into clamping engagement with the stem of a valve, thereby securing the valve in its closed, seated position. When the high fluid pressure is relieved, the valve stem is unclamped, and the valve can then be readily lifted to an open position.

  • Patent number: 5626164
    Abstract: A crack resistant valve plate assembly is provided for use in a slide gate valve. The valve plate assembly includes a refractory valve plate having an orifice positioned along its longitudinal center line, and truncated corners for focusing a clamping force toward the center line in the vicinity of the orifice to prevent the formation and spreading of cracks. The angular orientation of each of the truncated corners varies with respect to the position of the orifice along the longitudinal center line. Specifically, each of the truncated corners are orthogonal to a line extending from a point tangent with the orifice, across the center line, and through an intersection lines drawn parallel to the converging lengthwise and widthwise plate edges that is spaced from the edges a distance equal to one-half of the maximum diameter of orifice that the plate can effectively operate with.

  • Patent number: 5458151
    Abstract: A solenoid controlled valve is mounted in a threaded opening of a pressure vessel which contains compressed natural gas. The valve includes a valve body having a head, which is exposed outside of the pressure vessel, and a neck, which is located within the pressure vessel. A solenoid poppet valve is mounted to the inner end of the neck. A valve seat is mounted in a bore within the valve body. All orifice at an inner end of the valve seat exposes a flow passage between the bore of the valve body and an outlet port, which is located in the head of the valve body. The solenoid poppet valve includes a seal for closing the orifice, a bias spring which biases the seal toward the seat to close the orifice, a plunger which is connected to the seal, and a solenoid coil which, when energized, moves the plunger so that the seal moves out of engagement with the seat and permits flow of compressed gas from the interior of the pressure vessel to the outlet port.
