The suspension thrust bearing device for a motor vehicle comprises a rolling bearing 22 forming an axial thrust bearing and provided with an upper ring, with a lower ring and with at least one row of rolling elements arranged between the rings, a bearing cap 18 in contact with the upper ring, and a support cap 20 in contact with the lower ring and forming a bearing means for a suspension spring. The support cap 20 comprises a body 32 of rigid material and seals 46, 48 of flexible material fixed to the body and comprising dynamic sealing lips 56, 62 in frictional contact with the bearing cap or one of the rings of the rolling bearing and delimiting radially a sealed space 64 containing at least the rolling elements of the rolling bearing. The support cap 20 further comprises an annular ring 50 to which the lower ends of the seals are connected and forming a bearing surface 50a for the suspension spring.

Tensioning roller device including a non-rotating part about which there is rotationally mounted a pulley-forming rotating assembly designed to collaborate with a belt or a chain and a rolling bearing positioned between the non-rotating part and the pulley and including a rotating ring, a non-rotating ring and rolling elements, the pulley including a rigid rim including a first part fixed to the rotating ring of the bearing and a second part that can move with respect to the first part under the action of an elastic element, and an expandable sleeve of annular overall shape designed to be in contact with the belt or the chain, the diameter of the expandable sleeve varying according to how hard it is pressed by the second part.

An arm for an unwinder for unwinding rolls is disclosed. The arm includes an axial engaging member for engaging the rolls. The axial engaging member has a shaft supported by at least two support bearings mounted on the arm, so as to rotate around a rotation axis. A brake is also provided, adapted to act on the shaft. The brake is at least partially arranged between the two support bearings.

A versatile and easily serviceable material spreading apparatus of the type for movement over a ground surface while broadcasting a material along a path on the ground surface. The apparatus includes a belt cartridge which can be slid into or pulled out of a chassis compartment having ledges for supporting the cartridge. The belt cartridge provides an upper flight on which material is carried from a hopper supported on the chassis to a broadcasting unit carried at one end of the chassis. A plurality of broadcasting units each of which has an attachment component, which in combination with a mating attachment component carried by the chassis, permits quick fastening and removal of each unit relative to the chassis. One of the broadcasting units mounts an elongated rotatable member below a drop-off end of the upper flight of the belt cartridge, and the rotatable member is driven in a direction so that the upper rotating periphery of the rotating member propels the material upward and away from the chassis. The rotating member has strips of bristles which spiral around a core of the member towards opposite ends thereof so that the material also has imparted to it from bristles of the rotating member a direction of flight having a side-ways component to thereby increase the width of the path of distribution.

A valve for injecting fuel includes a valve carrier having a valve seat and an inflow orifice, a valve positioning member, and a flow limiting element that is disposed on the valve positioning member. The inflow orifice includes a step having a peripheral annular edge, and the flow limiting element is disposed on the valve positioning member in such a way that when the valve is opened, a flow area between the annular edge and the flow limiting element is reduced from a first flow area to a second flow area.

The invention relates to a stop valve (1, 1′, 1″) for a portable pressurized-gas container (35). A valve body (2) is provided with three connection adapters (7, 17, 18), i.e. one central connection adapter as a gas tank connection adapter (7), another connection adapter as outlet connection adapter (17) and a third connection adapter as spindle drive receiving adapter (18). Valve body (2) is made in several parts including valve body element (3) with the outlet connection adapter (17) and a spindle drive receiving adapter (18) and a radial valve seat element receiving bore (20) going to the bottom of the spindle drive receiving adapter (18). Furthermore, the valve body (2) has an oblong valve seat element (5) with gas supply bore (29) provided at the one end of the valve seat (30) and a bearing collar (26) on the other end. In its assembled state, the valve seat element (5) is inserted tightly into the radial bolt receiving bore (20). In addition, the valve body (2) has a main bolt (4) which is inserted tightly into the central main bolt receiving bore (19). Suitable gas supply bores (9, 11, 29) allow gas to flow from the connected pressurized-gas container (35) via the spindle drive receiving adapter (13) to the outlet connection adapter (17).

The present invention relates to a non-polluting thermal generator having a very good energy efficiency and a simple and economical design, low consumption of energy, all while being scalable, versatile and modular. In this thermal generator (1), the thermal elements (3) composed of magnetocaloric material each comprise two distinct collector circuits (31, 32), one hot collector circuit (31) being connected to a hot heat transfer fluid circuit (51) and one cold collector circuit (32) being connected to a cold heat transfer fluid circuit (52). The heat transfer fluid is set in alternating motion in one or the other collector circuit (31, 32) depending on whether the thermal elements (3) are subjected to or not subjected to the magnetic field generated by the magnets (40) rotating about a central axis (B) with regard to the thermal elements (3). The heat transfer fluid circuits (51, 52) are integrated, in part, in a plate (2) supporting the thermal elements (3) and are connected to external circuits comprising heat exchangers (55, 56) using the calories and the negative calories generated by the thermal elements (3). The applications of the invention include: heating, tempering, air-conditioning, and refrigeration in every industrial installation and every household application.
