Reciprocating pump subassembly

A piston 20 is axially displaceable in a liner 12 and is held captive by a tubular filter 80 which is fitted on the liner and which comprises an anti-loss device in the form of a ring 86a which has a smaller diameter than part of the piston 20 or a supporting ring 58 on the piston 20. The connection...

Beschreibung
Zusammenfassung:	A piston 20 is axially displaceable in a liner 12 and is held captive by a tubular filter 80 which is fitted on the liner and which comprises an anti-loss device in the form of a ring 86a which has a smaller diameter than part of the piston 20 or a supporting ring 58 on the piston 20. The connection between the filter 80 and the liner 12 may be an interference fit, or may be achieved by retaining a collar 96 of the filter 80 within a groove 95 of the liner 12 by caulking (97, figure 2) or edging (figure 3), or by a detent connection (104,106 figure 4). Such a subassembly facilitates assembly.
