Figure 1 is a longitudinal section of a plunger showing a valve lifting and holding device embodying my invention; Fig. 2 is a perspective view of the lifting and holding device; and Fig. 3 is a section on the line 33 1. A tubular plunger, a valve therein, the lower portion of the plunger having an interior annular flange provided with opposite notches, and a valve lifting and holding device consisting of a length of resilient metal slidable through said notches, and having up per depressions for engaging with the flange,
The plunger comprises an upper section 5 and lower depressions for engaging with the and a lower section 6, which are secured to flange. gether by screw-threads, in the usual man- 2.

member 6 forms a valve-seat for a puppet valve 9, and at the lower end of said member 6 there is an annular flange 10 provided with diametrically opposite notches 11 which forms guides for the valve lifting and holding devices consisting of a strip of resilient metal having side members 12, 13 connected at the lower portion by a cross-member 14. The side members 12 and 13 which are movable within the member 6 of the plunger are provided with inward depressions 15, below which are inward depressions 16.
