Abstract: A valve comprises a housing (1) having an inlet (4) and an outlet (5), and a pressure sensing port (8). A piston (6) slides in a part (3) of the housing (1) in response to a difference between a first fluid pressure at the pressure sensing port on the one side of the piston, and a second fluid pressure at the inlet and/or outlet on the other side of the piston (6). A valve member (7) carried by the piston is operable thereby to close the inlet (4) when said second fluid pressure is less than a value sufficiently greater than said first fluid pressure. The valve member (7) is movable with respect to the piston (6) to facilitate closing of the inlet (4), in response to a fluid flow from the housing (1) to the inlet (4), when the piston is not acting to close the inlet.

Abstract: A bumper for a motor vehicle includes a cross member which is disposed transversely to a side rail of a motor vehicle frame, and a crash box which is connected between the side rails and the cross member. The crash box is configured in fold construction from a metal sheet and has a sidewall which exhibits a roof-shaped structure. The sidewall includes at least one wall section which is inclined in relation to the horizontal midsection transverse plane of the crash box.

Abstract: A bumper for a motor vehicle includes a cross member disposed transversely to side rails of a motor vehicle frame and having a U-shaped cross section with a wall and two legs extending from opposite ends of the wall. The cross member is supported via integral crash boxes against the side rails. Each crash box has a cross member proximal end which abuts against the wall of the cross member, and includes vertical legs and horizontal legs to define a casing-like configuration. The wall of the cross member is formed in an area of the cross member proximal end of the crash box with a depression which extends in a direction of the crash box, with the vertical legs of the crash box joined at the cross member proximal end to the wall of the cross member, and with the horizontal legs of the crash box spaced from the wall of the cross member by a distance.

Abstract: A crash box for installation between a longitudinal member and a bumper cross member of a motor vehicle, includes a sheet metal body having a deformation member which extends anteriorly of an end surface of the longitudinal member and whose maximum crumpling capability defines the energy absorption of the crash box. In prolongation of the deformation member is an attachment member which is engaged in the longitudinal member and detachably secured by bolts therein. Formed in a transition zone between the deformation member and the attachment member, is a stop which is configured in the form of an outwardly directed material protuberance or outwardly directed thickened area of the sheet metal body and bearing against the end surface of the longitudinal member.

Abstract: An apparatus and method are provided for facilitating the cooling of engine coolant flowing through a radiator operatively connected to the engine of an engine-driven, electrical generator set. The engine has a crankshaft rotatable about a first axis and a radiator having a first side directed towards the engine and a second side. The apparatus includes a fan positionable on the second side of the radiator that is rotatable about a second axis generally parallel to and vertically spaced from the first axis. The apparatus includes a thermally responsive clutch having a driven portion. The clutch is movable between a first disengaged position wherein the driven portion is isolated from the crankshaft and a second engaged position wherein the driven portion rotates in unison with the crankshaft in response to a predetermined temperature. A fan drive system interconnects the driven portion of the clutch and the fan for translating rotation of the driven portion to the fan.

Abstract: A crash box for installation between a longitudinal member and a bumper cross member of a motor vehicle, includes a sheet metal body having a deformation member which extends anteriorly of an end surface of the longitudinal member and whose maximum crumpling capability defines the energy absorption of the crash box.

Formed in a transition zone between the deformation member and the attachment member, is a stop which is configured in the form of an outwardly directed material protuberance or outwardly directed thickened area of the sheet metal body and bearing against the end surface of the longitudinal member.

Abstract: A trailer coupler pivot assembly comprising a pivot mount member connected to a trailer frame member and a hinge bracket connected to a trailer tongue arm. The hinge bracket is pivotally connected to the pivot mount member so that the trailer tongue arm is pivotal relative to the trailer frame member between an open position and a closed position. However, either of the pivot mount member or the hinge bracket comprises a single, prefabricated component to make assembly more efficient and cost effective. With both the pivot mount member and the hinge bracket being single, prefabricate components, the trailer coupler pivot assembly can be more easily installed with fewer components and welds and by less skilled labor.

Abstract: A surge brake actuator is disclosed. The actuator includes an actuator housing and a coupler housing movably engaged within the actuator housing. Upper and lower coupler slide channels formed from a plastic material are releasably connected to the coupler housing and contact the actuator housing. The plastic coupler slide channels reduce frictional loss and provides superior brake actuation output when the coupler housing retracts into the actuator housing during braking. The surge brake actuator includes a push rod assembly that also provides superior brake actuation output to the actuator and can engage the actuator during a breakaway event. The surge brake actuator includes a releasably engagable reverse lock that prevents brake actuation while the towing vehicle moves in reverse.
