Definitions

  • the basic feature of the present valve is that the movable member, Le. the distribution piston, is subjected to radially balanced internal pressures, whereby, whatever the means for controlling it may be substantial forces are not required for displacements thereof, because it is highly slidable within the seating cylinder even on operation.
  • the present valve owing to its internal balance-can be controlled by a suitable electrovalve (core movement) through the difference in pressure provided by the compressor forming part of the unit.
  • the particular counterow circuit can be carried out indeed, owing to the provision of the present valve according to the invention.
  • the valve of course, is connected to several conduits, by which highly significant advantages are obtained as to eiiciency and operation, in addition to the practical advantage of removing a filter, two check 'valves and a thermostatic valve.
  • the valve comprises a cylinder, internally of which a core is adapted for a sealing movement, four longitudinal channels being formed in said core, two of these channels being peripheral at opposite locations and the other two internal are on a plane perpendicular to the plane of the former; four independent radial connecting members, two of which communicating with two inner channels; nine radial unions connecting the outer conduits communicating with the cylinder interior, six of said nine unions being coaxial ⁇ by pairs and coplanar on a plane perpendicular to the plane on which the other three unions are located, two of the latter in a coaxial pair on the same plane of the extreme right-hand pair in the other three pairs, the third union being located on the plane perpendicular to the extreme left-hand pair thereof.
  • the valve according to the present invention substantially provides a circuit attainable by a similar eleven-way valve, or four threeeway valves and a two-way valve suitably controlled and connected.
  • a further significant feature of the circuit as provided by the present valve is in the constantly unidirectional flow of the liuid, while cycle change is provided by varying the pressure areas and the physical state of the gas.
  • FIGS. 1 and 2 are mutually perpendicular longitudinal sectional Views of the valve, in which the core is moved to the left;
  • FIGS. 3 and 4 are two cross-sections of the same valve taken along lines 3 3 and 4-4 of FIG. 1, respectively;
  • FIGS. 5 and 6 are views similar to FIGS. l and 2, in which the core is moved to the right;
  • FIGS. 7 and 8 are two cross-sections of the same valve taken along lines 7--7 and 8-8 of IFIG. 5, respectively;
  • FIG. 9 shows a common direction inverting circuit
  • FIGS. l0 and 11 show the single direction circuit according to the present invention.
  • the nine-way valve comprises a cylinder 12, in which a core 13 is controllably moved, the sealing for said core being ensured by annular gaskets 14; provisions are made along the periphery of said core 13 for two diametrically opposite channels 15 and two inner channels 16, the latter being coplanar and symmetrical to the axis and perpendicular to the former, and adapted for communicating with the outside through sector connecting members 17 at the left end; said core 13 additionally has sector connecting members 18 at the right end and intermediate holes 19; all of these connections are coplanar in the sectional view of FIG. 1.
  • core 13 is adapted to be controlled from the outside by mechanical or pneumo-hydraulic means.
  • Cylinder 12 is made fast with a first set of six unions arranged in three coaxial and coplanar pairs 2021, 2021' and 20"-21"; said pairs are located at the middle portion of the cylinder and the mutual position thereof (FIG. l) is such that as the first and second pairs are connected by channels 15, the third pair communicates through sector connecting members 18 with the perpendicular and coplanar pair 22-23.
  • the connections will be as follows: the second and third pair (FIG.
  • a cycle inverting nine-way valve providing a heat and refrigerator pump circuit characterised in that said circuit is unidirectional for both cases, the valve comprises a cylinder in which a core can be moved to two extreme positions, in said core there are four longitudinal channels, two of which are peripheral and the other two internal; four independent radial connecting passages two of which communicate with the two inner channels; nine radial unions connecting the outer conduits communicating with the valve interior, six of which being coaxial by pairs and coplanar on a plane perpendicular to the plane containing the other three unions, two of the latter being coaxial and on the same plane of the rightmost pair of the other three pairs, Whilst the third union is on a plane perpendicular to the leftmost pair thereof.
  • a nine-way valve according to claim 1 characterized in that said two diametrically opposite and symmetrical peripheral channels extend so as to connect only two pairs of unions in both core positions.
  • a nine way valve according to claim 1 characterized in that said two inner channels, which are more extended than the former and moved to the left, have at the ends thereof substantially sector connecting members for a right angle interconnection of two adjacent unions.
  • a nine way valve according to claim 1 characterized in that the intermediate connecting members radially and coaxially extend by pair from the inner channels.
  • a valve according to claim 1 characterized in that in all cases the pressure distribution on said core by the fluid from the unions is so balanced that said core will move within said cylinder free of localized frictions.
  • a valve according to claim 1 characterized in that the sealing for said core is ensured by annular gaskets.
  • a valve according to claim 1 characterized in that the control for said core is carried out by any preferred means through the cylinder heads.
  • a heat and cold pump circuit provided by the valve according to claim 1, characterized in that by the provision of only one thermostatic valve and one iilter, the circuit provides for a unidirectional flow in both cases; and on cycle inversion said circuit has an additional parallel circuit for cancelling the resistance generated [by the change of the pressure area.
