Embodiment Construction

[0028] The roller lever valve 1 shown in the drawing has a valve unit 2 and a roller lever actuating device 3 for mechanically actuating the valve unit 2 .

[0029] The valve unit 2 has a longitudinal axis 4 . The roller lever actuation device 3 is preferably arranged on one of the two axial end sides of the valve unit 2 .

[0030] The valve unit 2 has a one-piece or multi-piece valve housing 5 , in which a valve chamber 6 is formed, in which a valve ring assembly 7 extends. In the present exemplary embodiment, the valve segment assembly 7 consists of a single valve segment 7a, but it can also comprise a plurality of valve segments. Within the range of the switching movement 8 indicated by the double arrow, the valve ring assembly 7 can be moved relative to the valve housing 5 in the axial direction of the longitudinal axis 4 and thus be switched between two switching positions. exist figure 2 and 3 In the first switching position of the valve link assembly 7 shown in the...

Abstract

The invention relates to a roller lever actuating device (3) and to a roller lever valve (1) equipped therewith. The roller lever actuating device (3) has a supporting base (22) and a roller lever (27) that can be pivoted in relation to the supporting base (22). The roller lever (27) can be pivoted from a base position into an actuation position, wherein the roller lever actuates a valve element assembly (7) of the roller lever valve (1). In the case of the opposite backward pivoting motion (33b), the roller lever (27) is braked by energy-absorbing means (55) of an energy-absorbing device (56)such that hard impacts and correspondingly heavy loading of the structure of the roller lever actuating device (3) are avoided.

Description

technical field [0001] The invention relates to a roller lever actuating device for a roller lever valve with a bearing base for fastening on a valve unit of a roller lever valve and a bearing base with drive rollers mounted pivotably with respect to a pivot axis on the bearing base Roller lever, wherein the roller lever is pivotable from a basic position into an actuating position in the range of a forward pivoting movement, and can be swiveled from the actuating position back into a basic position in a backward pivoting movement, wherein the roller The lever has at least one force output section spaced apart from the pivot axis, which is arranged to act in a pressing manner on the valve to be actuated associated with the roller lever valve in the case of a forward pivoting movement. On the control section of the link component. Furthermore, the invention relates to a roller lever valve equipped with such a roller lever actuating device. Background technique [0002] DE 1...
