摘要： A fitting for connecting pipes, in particular flexible pipes, includes a first tubular element provided with a first inlet/outlet opening and defining at its interior a first duct, and a second tubular element provided with a second inlet/outlet opening and defining at its interior a second duct. The two tubular elements are connected to each other in a manner such that the first and the second duct are in communication. The fitting includes a first bushing associated with the first tubular element in order to externally surround it and create an annular housing, which can operate in an insertion configuration, in which it allows the insertion of a pipe in the annular housing, and a clamping configuration, in which it presses and locks the pipe in a fluid-tight manner. The fitting includes a first bushing-holder externally associated with the first tubular element and configured for mounting the first bushing so that it defines the annular housing, including a seal portion externally wound around and in contact with a seal sector of the first tubular element. The seal portion is interposed between a portion of the pipe inserted in the annular housing and the seal sector, and attains a fluid-tight gasket when the first bushing is in clamping configuration, preventing the leakage of fluid between the first duct and the exterior of the fitting.

摘要： A fitting for connecting pipes, in particular flexible pipes, includes a first tubular element, provided with a first inlet/outlet opening and at its interior defining a first duct, and a second tubular element, provided with a second inlet/outlet opening and at its interior defining a second duct. The two tubular elements are connected together in a manner such that the first and second ducts are in communication. The first tubular element is provided with at least one through opening, between an external surface thereof facing outwards and an internal surface directed towards the first duct. The through opening defines a respective empty space between the external surface and the internal surface of the first tubular element. The fitting operates in an insertion condition, in which it allows a pipe to be fitted around said first tubular element, and a clamping condition, in which the pipe is pressed and stably locked on the first tubular element. In the clamping condition, the empty space defined by the through opening is occupied by a portion of the pipe pressed on the first tubular element.

摘要： A manifold for the distribution of a fluid in a plumbing and heating system has a tubular shape and defines in its interior a distribution conduit for the fluid. The manifold extends between a first inlet/outlet end and a second inlet/outlet end, both of which are designed to put the distribution conduit in communication with the exterior of the manifold to receive incoming fluid or to send fluid exiting the manifold. The manifold comprises a plurality of branches arranged in series along a longitudinal extension and interposed between the first and second inlet/outlet ends, wherein each branch allows a quantity of fluid to enter into or exit from the distribution conduit. Each branch is provided with an access or exit opening having a respective axis, and the branches are positioned in the manifold in such a way that: the distance between the first inlet/outlet end and the axis of the first branch is equal to an initial stretch, the centre-to-centre distance between the axis of each branch and the axes of the adjacent branches is equal to a centre-to-centre distance measurement between the branches, and the distance between the axis of the last branch and the second inlet/outlet end is equal to a final stretch. The length of the final stretch is equal to the sum of the length of the initial stretch and half of the centre-to-centre distance measurement.

摘要： A heat machine for realizing a heat cycle, operating with a thermal fluid includes a drive unit. A first rotor and a second rotor, each having three pistons slidable in an annular chamber, wherein the pistons delimit six variable-volume chambers. The drive unit includes a transmission to convert the rotary motion with first and second periodically variable angular velocities of said first and second rotor, offset from each other, into a rotary motion at a constant angular velocity. The heat machine further includes a compensation tank, to accumulate the compressed fluid from the drive unit, a regenerator to preheat the fluid, a heater to superheat the fluid circulating in the serpentine coil, a burner, to supply the thermal energy to the heater; wherein the regenerator, in fluid communication with the drive unit, is configured to acquire energy-heat from the exhausted fluid and to preheat the fluid sent to the heater.

摘要： A new combined SEOL cycle is represented by the recovery vapor Generator (GVR) which completely substitutes the Regenerator, of the prior art, being capable of recovering the energy differential (QR) between the temperature at the end of expansion and the temperature at nearly complete condensation of the thermal fluid and then, by using this great energy differential, it is capable of producing water vapor, entirely reusable in the preheating of the mixture, considerably contributing to the increase of the overall energy yield of the cycle and to the increase of the unit power of the heat engine.

摘要： An apparatus for controlling the distribution of a fluid along a supply line configured to supply a user includes a first hydraulic valve located along the supply line and provided with an inlet, which receives fluid in transit in the supply line; an outlet, which transmits fluid through the first valve to make it continue along the supply line, or which receives fluid coming from a portion of the supply line downstream of the first valve; and a discharge, which discharges outside of the supply line, through the first valve, fluid present in the supply line and coming from a portion of the supply line downstream of the first valve. A second hydraulic valve is operatively located along the supply line at a point downstream from the first valve and provided with an inlet, which receives fluid coming from the outlet of the first valve; an outlet, which transmits fluid through the second valve to make it continue along the supply line; and a bypass inlet, which receives fluid drawn from the supply line at a withdrawal point upstream of the first valve and brought directly to the second valve by means of a bypass duct branching off from the supply line upstream of the first valve.
