A valve assembly (35) for pumps (10) is described, comprising:a first chamber (45) adapted to be placed in fluid communication with an inlet duct, a second chamber (50) communicating with the first chamber (45) via a first valve seat (55), the second chamber (50) being adapted to be placed in fluid communication with an outlet duct, a first shutter body (60) housed in the second chamber (50) and movable between a closed position, in which it closes the first valve seat (55), and an open position, in which it opens the first valve seat (55), a first resilient element (65) adapted to push the first shutter body (60) towards the closed position in contrast to the pressure present in the first chamber (45), an additional chamber (175) in fluid communication with the second chamber (50) via an additional valve seat (180), an additional shutter body (C) housed in the additional chamber 175, where it is movable between a closed position, in which it closes the additional valve seat (180), and an open position, in which it opens the additional valve seat (180), an additional resilient element (185) adapted to push the additional shutter body (C) towards the closed position,wherein the additional shutter is movable, in contrast to the spring force of the additional resilient element (185), from the closed position to the open position if the pressure difference between the second chamber (50) and the additional chamber (175) is greater than a threshold value.

A valve assembly (35) for pumps (10) is described, comprising:a first chamber (45) adapted to be placed in fluidic communication with an inlet duct (A), a second chamber (50) communicating with the first chamber (45) via a first valve seat (55), the second chamber being adapted to be placed in fluidic communication with an outlet duct (B), a first shutter body (60) housed in the second chamber (50) and movable between a closed position, in which it closes the first valve seat (55), and an open position, in which it opens the first valve seat (55), a first resilient element (65) adapted to push the first shutter body (60) towards the closed position in contrast to the pressure present in the first chamber (45), a discharge duct (110) communicating with the first chamber via a second valve seat (115), a third chamber (130) communicating with the second chamber (50) and partially delimited by a sliding plunger (140), a second shutter body (125) connected to the plunger (140) and housed in the first chamber (45) where it is movable between a closed position, in which it closes the second valve seat (115), and an open position, in which it opens the second valve seat (115), and a second resilient element (155) adapted to push the second shutter body (125) towards the closed position in contrast to the pressure present in the third chamber (130), an additional chamber (175) at least partially formed in the plunger (140) and placed in fluidic communication with the third chamber (130) by means of an additional valve seat (180), the additional chamber (175) also having an outlet port (215) by means of which it is in fluidic communication with the first chamber (45).

A steering apparatus (100) is described which is provided with: a drive shaft (105) rotatably coupled to a support structure (190) and comprising at least a first segment (175), a second segment (180), and a torsion bar (185) which is placed to connect the first segment (175) to the second segment (180) allowing them relative angular offsets; a device (110) adapted to transform a rotation of the drive shaft (105) into a displacement of at least one steering member (115) of a vehicle; an electric motor (200) adapted to apply torsional torques to the drive shaft (105); two angular position sensors, of which a first angular position sensor (220) adapted to detect the angular position of the first segment (175) of the drive shaft (105) with respect to the support structure (190), and a second angular position sensor (265) adapted to detect the angular position of the second segment (180) of the drive shaft (105) with respect to the support structure (190); and an electronic control and command unit (215) configured to control the operation of the electric motor (200) based on the readings made by said first and second angular position sensors (220, 265).

A method and a plant for the manufacture of capsules (500) for the preparation of beverages are described, comprising at least the steps of: arranging a first strip (530) of a cellulose-based material, obtaining from said first strip (530) a plurality of concave capsule bodies (505), each of which defines an internal volume (515) open at a mouth (520), filling one or more of said capsule bodies (505) with a dose of an edible substance adapted to make the beverage, and sealing the mouth (520) of the filled capsule bodies (505), with a lid (510) of a cellulose-based material; wherein the step of obtaining the capsule bodies (505) provides for: engaging said first strip (530) to slide in a preset path, along which it has at least one stretched section (540), pressing said stretched section of the first strip (530) by means of a shaped mould (115) adapted to deform one or more portions of said stretched section (540), giving each of them a concave shape defining a respective capsule body (505), and separating each of said portions from the first strip (530).

A squaring machine (10) for processing slabs (15) is described, comprising: - a base frame (20); - a pair of side banks (30) supported by said base frame (20) and movable in reciprocal approach/distancing along a horizontal reciprocal flanking direction (B), wherein each side bank (30) carries: o a series of spindles (50) each having an abrasive tool (60) rotating about a respective rotation axis (R); and o at least one conveyor (35), wherein said conveyors (35) carried by the side banks (30) provide a movable support surface (25) adapted to receive and move at least one slab (15) or a succession of slabs (15) along a horizontal advancement direction (A) orthogonal to the flanking direction (B); - a fairing (105) supported by the base frame (20) and delimiting a processing compartment (115) where at least some of said spindles (50) are accommodated.
