Patent number: 11209109Abstract: A crimp coupling includes a crimping ferrule for connecting a hose to a fitting. The fitting includes an outwardly projecting stop collar and a groove which extends circumferentially around the fitting at a constant axial distance to the stop collar. The crimping ferrule, which can be slid onto the fitting, includes a flange, a tapering hinge section, and a cylindrical section. A distance between the stop collar and the groove of the fitting is dimensioned such that the flange, when abutting the stop collar, has a lower edge facing away from the stop collar above the groove. Due to a diameter reduction of the cylindrical section and the tapering hinge section, during crimping, the flange is pivoted such that the lower edge of the flange is turned into the groove by the pivotal movement of the flange.Type: GrantFiled: February 16, 2018Date of Patent: December 28, 2021Assignee: KA Group AGInventor: Laurentius Andreas Gerardus Mentink

Patent number: 7194947Abstract: A hydraulic actuating device for moving a retractable hard-top of a convertible car. The actuating device comprises a double-acting hydraulic actuator, the first connection of the actuator being in communication with an associated throttling assembly which is designed to provide either an optionally controllable throttling or a clear passage opening, which is larger than the throttling opening, as a function of a switching parameter. The throttling assembly has a pressure-detection means for detecting the hydraulic pressure in the second working chamber, which pressure-detection means has associated with it a predetermined switching pressure. The throttling assembly is designed such that—when pressurized hydraulic fluid is supplied to the second working chamber—the clear passage opening is active if the detected pressure in the second working chamber is above the switching pressure and that the throttling is active if the detected second working chamber hydraulic pressure is below the switching pressure.Type: GrantFiled: June 1, 2004Date of Patent: March 27, 2007Assignee: Actuant CorporationInventor: Laurentius Andreas Gerardus Mentink

Patent number: 6739235Abstract: A hydraulic control device having a hydraulic actuator with a cylinder space, in which a piston is accommodated. In the cylinder space the piston bounds a first chamber and second chamber. The housing is provided with a first and a second connection for the supply and discharge of hydraulic fluid, in communication with the first and the second chamber by way of a first and a second opening. The damping means are achieved by the fact that the piston is provided with shut-off means, which are designed to shut off the second opening of the cylinder space before the piston/piston rod assembly reaches an end position. The hydraulic actuator is further provided with a third connection, which by way of a third opening is in communication with the second chamber in any position of the piston. The hydraulic control device further comprises a throttling facility.Type: GrantFiled: July 8, 2002Date of Patent: May 25, 2004Assignee: Actuant CorporationInventor: Laurentius Andreas Gerardus Mentink
