Embodiment Construction

[0044] Exemplary embodiments of the valve according to the invention are described below, which partially have identical or similar components, which are identified with the same reference numerals. according to Figure 1-4a The valve 10 is set to operate on the valve bank. according to Image 6 , 7 and 8 valves 110 form a single valve. Parts of the components arranged inside the valve 10 are not visible and are described in connection with the valve 110 .

[0045] The valves 10 , 110 are used for fluidically operating a power tool 11 , such as a pneumatic working cylinder. The valves 10 , 110 have valve housings 12 , 112 which comprise a basic housing 13 , 113 and which are closed at the end faces 14 , 15 with a cover 17 or 117 .

[0046] In the valve 10 , 110 , the valve mechanism 19 is moved back and forth in the valve chamber 18 along the longitudinal axis 20 . The valve mechanism 19 has pistons 21 , 22 , in particular on the end side, which are driven pneumatically,...

Abstract

The invention relates to a valve for triggering working apparatus of liquid technique. The said valve has a base housing with a valve chamber. A valve member is movable back and forth in the valve chamber for affecting a fluid-connection between connections. At least one cover for locking the valve chamber is in the valve. The cover is arranged at the base housing by a plug-in connection, with which a cover-plug-in connection section of the cover and a base housing-plug-in connection section of the base housing, are stuck into one another. A spring dowel pin is pressed into fixing channel, interspersing the plug-in sections transverse to longitudinal axis and stretches at least one cover toward the base housing

Description

technical field [0001] The invention relates to a valve for actuating a fluid-technical work tool, the valve having a basic housing with a valve chamber in which a valve mechanism is movable back and forth along the longitudinal axis of the valve chamber For influencing a fluid connection between connections for connecting the power tool, the valve also has at least one cover for locking the valve chamber. Background technique [0002] The power tool is, for example, a pneumatic cylinder, which is connected to a working connection of the valve. The basic housing has a valve chamber, the valve mechanism moves on the longitudinal axis of the valve chamber. The valve mechanism has, for example, a longitudinal configuration and penetrates from the end face into the valve chamber, which is then closed with one or two caps on the end face. The cover is usually screwed onto the basic housing or fixed by means of a valve chamber holder. [0003] When installing the cover, it shou...
