Abstract: Installation (1) for blow molding hollow bodies, comprising at least one mold carrier (2) to which a removable mold (3) can be connected via fluid connection means (4), at least one pressurized temperature-controlled fluid circuit (5) passing through the carrier and mold, and automatic circuit (5) shutoff means provided in the carrier (2); which circuit (5) has a fluid connection to at least one chamber (8) having a variable volume that depends on an external pressure applied to said chamber (8) by means (9) for generating an auxiliary fluid at a pressure that is adjustable between the pressure of the temperature-controlled fluid and atmospheric pressure, by means of which the pressure of the pressurized temperature-controlled fluid can be reduced in said chamber (8) by decompression.

Abstract: A hopper-type tank (1) for storing and dispensing solid bodies, the tank having a wall (3) on the inside face of which is fastened a plurality of obstacle members (4) situated in different planes and forming a mesh inside the tank (1), each obstacle member (4) having a substantially long and thin general main shape extending across the inner space of the tank, the obstacle member (4) extending between two locations of the inside face of the wall (3) of the tank (1); the tank has at least one first set of obstacle members (4) placed along a first direction in a first plane, and at least one second set of obstacle members (4) placed along a second direction, different from the first direction, in a second plane, thereby enabling the fall of solid bodies tipped in bulk into the top portion of the tank (1) to be slowed down.
