Abstract

A telescopic fitment is provided for connection of a magnetic filter into a central heating system circuit, telescopic fitment including a first connector and a second connector, each of the first and second connectors including a filter connection end for connecting with the magnetic filter and a circuit connection end for connecting with the central heating system circuit, at least one of the first and second connectors including an inner pipe and an outer pipe, the filter connection end being provided on one of the inner or outer pipes and the circuit connection end being provided on the other of the inner or outer pipes, the inner pipe being slideable within the outer pipe for adjusting the position of the circuit connection end with respect to the filter connection end, whilst maintaining a sealed fluid path between the circuit connection end and the filter connection end.

Claims

1. A telescopic fitment for connection of a magnetic filter into a central heating system circuit,

the telescopic fitment including a first connector and a second connector, the first connector and the second connector each including a filter connection end for connecting with the magnetic filter and each including a circuit connection end for connecting with the central heating system circuit,

at least one of the first connector and the second connector including an inner pipe and an outer pipe, the filter connection end being provided on one of the inner or outer pipes and the circuit connection end being provided on the other of the inner or outer pipes,

the inner pipe being slideable within the outer pipe for adjusting the position of the circuit connection end with respect to the filter connection end, whilst maintaining a sealed fluid path between the circuit connection end and the filter connection end.

2. A telescopic fitment as claimed in claim 1, in which locking means are provided, the locking means being engageable to prevent sliding of the inner pipe with respect to the outer pipe following sliding of those pipes to an extended position, a retracted position, or any intermediate position.

3. A telescopic fitment as claimed in claim 2, in which the locking means include a threaded collar for engaging with one or both of threads provided in fixed longitudinal positions on the outer and inner pipes.

4. A telescopic fitment as claimed in claim 1, in which the circuit connection end of each of the first and second connectors is provided with a straight female thread.

5. A telescopic fitment as claimed in claim 1, in which the filter connection end of each of the first and second connectors is provided by the inner pipe and the circuit connection end of each of the first and second connectors is provided by the outer pipe.

6. A telescopic fitment as claimed claim 1, in which at least one of the outer pipe and the inner pipe is substantially in the form of a 90 degree elbow, the filter connection end and the circuit connection end of the connector facing in substantially perpendicular directions.

7. A telescopic fitment as claimed in claim 1, in which an O-ring seal is provided between the inner pipe and the outer pipe of each telescopic connector.

8. A telescopic fitment as claimed in claim 7, in which a second O-ring seal is provided between the inner pipe and the outer pipe of each telescopic connector.

9. A telescopic fitment as claimed in claim 7, in which the O-ring seal(s) are provided in one or more grooves on the inner pipe, and in which the outer pipe has a substantially smooth inside wall which slides adjacent the O-ring seal in use.

10. A telescopic fitment as claimed in claim 1, in which a stop is provided between the inner pipe and the outer pipe, to prevent the outer and inner pipes from becoming detached from each other.

11. A telescopic fitment as claimed in claim 10, in which the stop is in the form of a snap ring held within a holding groove near the end of the outer pipe, and a first detent on the exterior wall of the inner pipe.

12. A telescopic fitment as claimed in claim 11, in which a snap-ring assembly groove is provided on the exterior wall of the inner pipe, inward of the first detent.

13. A telescopic fitment as claimed in claim 12, in which an extension forming a second detent is provided around the external wall of the inner pipe, inward of the snap-ring assembly groove.

14. A telescopic fitment as claimed in claim 11, in which the outer pipe has a tapered mouth at one end.

15. A telescopic fitment as claimed in claim 14, in which the holding groove on the outer pipe is located inward of the tapered mouth.

16. A telescopic fitment as claimed in claim 1, in combination with a magnetic filter, the magnetic filter including inlet and outlet ports which extend from the filter substantially parallel with each other.

17. A telescopic fitment and a magnetic filter as claimed in claim 16, in which the magnetic filter includes a filter body made substantially from plastics or glass-reinforced nylon.

19. A telescopic fitment and a magnetic filter as claimed in claim 16, in which the inlet and outlet ports are externally screw-threaded for connection with the filter connection ends of the first connector and the second connector.

20. A method of fitting a magnetic filter to a pair of pipe ends in a central heating system circuit,

the method making use of a telescopic fitment according to claim 1, the circuit connection end of each of the first connector and the second connector being an internally threaded screw connection,

and the method comprising the steps of:

a) cutting a tapered thread in each of the pipe ends;

b) screwing the internally threaded circuit connection of each of the first connector and the second connector onto the tapered thread of a respective pipe end;

c) adjusting the position of the filter connection ends of the first connector and the second connector by sliding the inner pipe and the outer pipe of the fitment to position the filter connection ends spaced from each other at a distance matching the distance between the inlet port and the outlet port of the magnetic filter;

d) attaching the filter connection end of the first connector and the second connector respectively to the inlet/outlet port of the magnetic filter.

21. A method according to claim 20, further comprising the step of engaging locking means to prevent sliding of the inner and outer pipes of each connector of the fitment relative to each other.
