  • Publication number: 20180334521
    Abstract: The present invention relates to a vulcanizable composition comprising a specific block copolymer thermoplastic elastomer, a polyolefin, a rubber softener, a crosslinking agent and a specified liquid diene rubber crosslinking co-agent, and a dynamically vulcanized composition produced by intimately mixing the above components under shear and at elevated temperature, which dynamically vulcanized composition is thermoplastic, elastic and moldable.

  • Patent number: 9948154
    Abstract: An electronically commutated DC motor has a stator wound with a multi-phase stator winding, a permanent magnet rotor mounted rotatably about a motor axis, a circuit board, a guide plate electrically connected to the winding and a housing component. In one implementation, a DC motor can easily be manufactured with the fewest possible process steps, which exhibits a short axial length and a low weight as well as good heat-dissipation properties. It is also an object of the invention to create a DC motor with integrated electronics, whose motor interior can be filled with oil, and which holds the electronics sealed against this oil. For reasons of logistics, an attempt is also made for partial components, such as the electronics, to be designed such that they are capable of complete prior assembly and testing.

  • Publication number: 20100326543
    Abstract: A pressure control valve for at least one of controlling and/or regulating a pressure level in a hydraulic circuit. The control valve comprises a valve housing (1) in which a control element (2), that can be acted upon by a system pressure (P_Sys), is arranged to move. The control element (2) is coupled to a drive mechanism in order to set an operating pressure (P_Kpl). At least one linear motor (3) is provided as the drive mechanism which can be controlled at least by a signal feedback (4) acting as a control circuit as a function of the operating pressure (P_Kpl) actually set at the time.

  • Publication number: 20100243079
    Abstract: An arrangement of a pressure limiting valve (1) for the pilot control of a pressure control valve of a hydraulically actuatable shifting element of a motor vehicle transmission in which the pressure limiting valve (1) is disposed such that the armature axis thereof is disposed perpendicular to at least one of the driving direction and the longitudinal axis of the vehicle.

  • Patent number: 7377160
    Abstract: A sensor arrangement (1) for a tachometric sensor of an automatic transmission (4) of a motor vehicle, which encompasses a module carrier (2) in which a part of a sensor housing (3) is integrated. The sensor housing (3) is secured in the module carrier (2) or in the transmission housing (4) by way of a guide in the plane and is so affixed as to prevent turning and an apparatus (5) for the generation of a prestress force by way of which the sensor housing (3) is pressed in the direction of the signal disk by way of a projection (8, 8?) acting against the sensor housing (3).

  • Patent number: 6966876
    Abstract: A device for holding and positioning an endoscopic instrument introduced through a body surface of a patient has a holder for the instrument, which holder is designed in such a way that the instrument can be positioned relative to the body surface in different spatial tilt positions. The holder has a first bow-shaped element whose two end portions are arranged directed towards the body surface, and whose middle portion is directed away from the body surface, the first bow-shaped element being pivotable about a first pivot axis which extends through both end portions.

  • Patent number: 6902405
    Abstract: A simulator apparatus with at least two degrees of freedom of movement for an instrument that has an elongated shaft, having a holding device for the instrument, the holding device being designed such that the instrument has at least a first degree of freedom of a swiveling movement about a first swivel axis and at least a second degree of freedom of swiveling movement about a second swivel axis, running perpendicular to the first swivel axis. The holding device has a cardanic suspension that has a spherical element which is suspended such that it can rotate about the first swivel axis and about the second swivel axis, and in which the shaft is partly held.

  • Patent number: 6786727
    Abstract: A simulator apparatus with at least two degrees of freedom of movement for an instrument which has an elongated shaft, has a holding device for the instrument, the holding device being designed such that the instrument has at least a first degree of freedom of rotary movement about the longitudinal axis of the shaft and at least a second degree of freedom of translatory movement in the direction of the shaft. The holding device has a gear arrangement for the first and second degrees of freedom, which has a first bevel gear, which is connected to the shaft and corotates with the latter about the longitudinal axis thereof, and has a second and a third bevel gear which are arranged on either side of the first bevel gear and are in rolling engagement therewith.
