Abstract: An installation for treating arthropod larvae, in particular, insects, and more specifically, ground Diptera larvae, comprises at least one piece of equipment producing glue water, which is extracted from the mixture of ground, larvae. The installation comprises a glue water circuit supplying a ground larvae treatment equipment comprising a circuit for diluting the ground larvae and/or a glue water evaporator and/or a meal dryer.

Abstract: A shock absorber of the invention comprises a strut, a inner cylinder fixed to the strut and extending inside the strut, and a sliding cylinder mounted to slide inside the strut and associated with the inner cylinder to communicate with the inside thereof via throttling orifices and short-circuit orifices, a pump and control arrangement being provided to pump hydraulic liquid from the sliding cylinder into the inner cylinder so as to produce a retraction of the sliding cylinder into the strut when both the throttling and short-circuit orifices are closed. The throttle orifices produce a communication between the sliding cylinder and the inner cylinder which produces a normal damping operation of the strut while the short-circuit orifices provide a rapid release of the sliding cylinder from a retracted position and a control member selectively closes one or both of the orifices.
