    • New A plunger having a cylindrical hollow body 20 or 20B , a handle 30, 30A, or 30B , an outlet hose 40 , an outlet tip 42 , and a valve or flap 50, 60, or 70 structure that is able to controls the air flow within the hollow 25 portion of the cylindrical body 20 or 20B is shown. The valve or flap 50, 60, or 70 structure is moved into a closed position so that air is forced out of the front of the plunger and towards a clogged or stopped area 82 or 92 and is moved into an open position so that air enters the back of the plunger and passes proceeds past the valve or flap 50, 60, or 70 structure, so that water and/or clogging material is not drawn or sucked into the interior of the plunger. F The hose attached to the cylindrical body is flexible and is smaller in diameter than the drain throat of a plumbing fixture allowing the hose to be placed into a clogged area. A first embodiment plunger 10 discloses shows a flexible valve flap 50 that compresses against the inner wall of the cylindrical body 20 when in a closed position and flexes outwardly and away from piston plate 38 when in an open position. S A second embodiment plunger discloses shows a circular valve plate 60 that slidingly fits within inner portion of piston plate 38 wherein such that the valve plate 60 is coupled to and controlled by handle control mechanism 64 .

    • A jerk pump provided for an internal combustion engine has an integral solenoid valve in which a pump plunger driven by a cam delivers fuel at high pressure through a channel that extends in the pump housing and through an injection line to an injection nozzle. An armature of the solenoid valve cooperates with a spring-loaded valve piston by which the channel-guiding high-pressure side can be connected with a low-pressure side. In order at least largely to avoid rebounding of the solenoid valve in such jerk pumps, provision is made such that the valve piston has an absorbent body held in its resting position by spring force, said absorbent body striking a stop body that holds the valve piston in its closed position when the valve piston is resting on its valve seat.
