  • Publication number: 20240157762
    Abstract: The invention relates to a thermal conditioning system including a refrigerant circuit having: a main loop including in succession: a compression device, a condenser configured to exchange heat with a first heat transfer fluid, a first expansion device, a first evaporator, a bypass branch including a second expansion device and a second evaporator. The second expansion device is a thermostatic expansion valve configured to vary a flow area for the refrigerant between a minimum flow area and a maximum flow area. The bypass branch includes a flow restriction device configured to limit a flow area for the refrigerant to a value less than the maximum flow area of the second expansion device.

  • Patent number: 9738235
    Abstract: To mount a unit in a compartment in a vehicle instrument panel including an opening for inserting the unit, the unit includes two tenons that are compressible in a heightwise direction and can be guided in two fixed parallel longitudinal lateral slideways that include an entry zone and a closed-end zone that is not as tall as the entry zone in which the tenon is compressed vertically. A facade surround is provided around the opening to collaborate in positioning and/or attachment of a face plate of the unit. The lateral slideways include two longitudinally separated parts, a first part secured to the facade surround and a second part not secured to the facade surround and held on a wall of the compartment of the instrument panel to lie substantially in longitudinal continuation of the first part.

  • Patent number: 7654005
    Abstract: An assembly having a first piece and a hollow second piece, the first piece having upper and lower parts which are connected by a hinge-forming part and form a space, a part of the second piece being accommodated in the space, the hollow second piece includes a cavity and a bushing is provided in at least part of the cavity, the bushing being provided at a level of a part of the hollow second piece that is accommodated in the first piece. The assembly further has a clamping unit that brings together the upper and lower parts of the first piece. The assembly relates in particular to the manufacture of tools for cutting, shearing, clamping or gripping, such as pruning shears. The assembly also concerns an assembly kit and a method for achieving an assembly.

  • Patent number: 7275475
    Abstract: A pressurized-medium-driven apparatus including an actuator articulately mounted a line segment and a connecting element. The line segment and the connecting element are connected so as to be mutually pivotable with respect to each other around a swing axis. The connection is provided by a junction means between the line segment and the connecting element, wherewith the connecting element and or the line segment are rigid components, preferably a rigid tube or pipe. The junction means is a swiveling junction connection.

    Abstract: The invention concerns an assembly having a first piece and a hollow second piece, the first piece having upper and lower parts which are connected by a hinge-forming part and form a space; a part of the second piece being accommodated in said space; the hollow second piece being provided in part of its cavity, at the level of its part accommodated in the first piece, with a bushing. This assembly further comprises clamping means which bring together said upper and lower parts of the first piece. The invention relates in particular to the manufacture of tools for cutting, shearing, clamping or gripping, such as pruning shears. The invention also concerns an assembly kit and a method for achieving an assembly.

  • Patent number: 7001136
    Abstract: The invention pertains to a device for attaching an implement to a lifting unit, in particular, to a front-end loader, wherein the implement and the lifting unit can be connected to one another by a movable bar that can be displaced from a locking position into an unlocking position by an externally activated actuator. The actuator is coupled to the bar by a coupling device designed such that a driving connection between the actuator and the bar is only produced when the actuator is activated. This makes it possible to displace the bar manually, as well as in an actuator-operated fashion.

  • Patent number: 7001137
    Abstract: The invention concerns an arrangement for the securing of an implement to a lifting arm, particularly to a front loader, where the implement and the lifting arm can be fastened to each other by a movable locking bar, which can be moved between a locking position and an unlocking position, and can be brought from the locking position into the unlocking position by a remotely actuated hydraulic cylinder. It is proposed that the locking bar can be arrested automatically in the unlocking position, with it then being possible for the hydraulic cylinder to be deactivated. The locking bar is located such that it can be brought into the locking position from its arrested position by moving the implement by another remotely actuated hydraulic cylinder such that the locking bar engages the lifting arm and is moved to a non-arrested position from where it is automatically biased back into its locking position.
