A valve assembly () is adapted to be coupled with a flexible pipe (). The valve assembly () includes a hollow body () defining a first end () and a second end (). A porous body () partially encloses the hollow body () proximate to the first end () and houses a swellable material (). The hollow body () further defines a hollow chamber () between the first and second ends (). A piston () is disposed within the hollow chamber (). The piston () is adapted to move between a first position (P) and a second position (P) corresponding to a contraction and an expansion of the swellable material (). The valve assembly () selectively allows passage of water through the flexible pipe () based on the positions (P. P) of the piston (). The irrigation system () is characterized in that the valve assembly () further includes an elastic diaphragm () disposed between the swellable material () and the piston (). The elastic diaphragm () includes an annular bead ().

For manually actuated shears with a ratchet mechanism it is proposed to provide an additional lever that circumvents the ratchet mechanism and enables the operation of the shears in a direct cut mode in which a single closing process of the handle levers also causes complete closing of the blade arrangement.

A cutting chain () moving in a cutting direction () is disclosed in the present invention. The cutting chain () includes a cutting link (), which further includes a cutting portion (), a depth gauge () and a space () between the cutting portion () and the depth gauge (). The cutting chain () further includes a bumper drive link () which is pivotally connected to the cutting link () and immediately precedes the cutting link () in the cutting direction (). The bumper drive link () further includes a tail () and a body (). The tail () of the bumper drive link () further includes a bent portion () and a straight portion (). Further, the bent portion () is oriented in a substantially perpendicular direction relative to a plane (P) of the body () of the bumper drive link (). Moreover, the bent portion () of the tail () extends into the space () between the cutting portion () and the depth gauge () of the cutting link ().
