A valve of a hydraulically striking device having a housing, the housing comprising a moving member being seated inside the housing to move in a reciprocating manner by means of a hydraulic fluid. The moving member has an inner space, the valve has a return space and a pressure space provided, in the axial direction, at a distance from one another on the inner surface of the housing facing the moving member, wherein the rest of the inner surface of the housing in the same axial positions of the return space and the pressure space forms guide surfaces that are concentric with the moving member and against the moving member for centering the moving member.

Provided is a safety valve (10) comprising a body (12) which defines an incoming fluid passage (14) and a return fluid passage (20). The incoming fluid passage (14) generally enables a fluid to pass from a fluid reservoir (18) through the body (12) to the tool head (16). The return fluid passage (20) generally enables a fluid to return from the tool head (16) through the body back to the fluid reservoir (18). The body (12) further comprises a diverter (22) which is displaceable between an active position and an inactive position. When the diverter (22) is in the active position, the diverter (22) redirects the fluid via a shunting passage (24) from the incoming fluid passage (14) to the return passage (20) to prevent operation of the tool head (16).

A dosing unit for dosing fluids includes a fluid guiding module having a fluid inlet and a fluid outlet, a solenoid valve for controlling or regulating a fluid flow through the fluid guiding module, and a dosing tip, the fluid outlet of the fluid guiding module leading to the fluid inlet of the dosing tip, and the dosing tip having an elastic, self-closing outlet nozzle. Furthermore, a dosing station and a dosing tip are specified.

A self-energized programmable timer valve is provided in embodiments of this invention that can be used in watering and other systems, such as lawn watering systems and agricultural watering systems. The invention provides one or more components that serve the functions of a clock, a valve and an energizer (e.g., turbine) (i.e., a clock function, a valve function, and an energizing and/or turbine function) to control the flow of media (e.g., water) through the valve. Exemplary components comprise a programmable clock apparatus comprising a mechanical clock mechanism and a mechanical mainspring, the programmable clock apparatus capable of opening and closing a control valve system by using a first connecting apparatus; the first connecting apparatus which converts the rotational movement of an of an hour dial and a minute dial to a linear movement of a valve plug component to open and close the control valve system and control the flow of media through it; and a turbine apparatus comprising a turbine shaft that has a turbine impeller on one end that is capable of turning when water flows through the control valve system, wherein when the turbine impeller turns its rotational energy is transferred to the mechanical mainspring of the programmable clock apparatus.

A double action directional fluid flow valve includes a stepped piston connected with a poppet valve and moveable by a controller between open and closed positions by applying a continuous pressure to a small diameter piston face and selectively applying and removing pressure from a large diameter piston face to move the poppet valve between an open position and a closed position.

An electromagnetically actuated valve. The electromagnetically actuated valve with a small longitudinal extension, allows great through-flow quantities for the fluid with a small pressure difference. It is intended in this case that it should be producible cost-effectively in large unit numbers. An armature carries a plurality of valve bodies arranged in a point-symmetrical manner which together form a movable valve, wherein the plurality of valve bodies interact with a same plurality of valve seats which together form a stationary valve. The valve can be used along with a pump, a tank and/or other fluid units in assemblies for conveying mixtures of gas and liquid.
