摘要： 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 . H The handle control mechanism 64 controls and places the valve plate 60 in either a closed position or an open position. T A third embodiment plunger discloses shows a handle 30B having piston plate 38 with that rotatingly engaging es a first set of tab portions 37 and a flexible valve flaps 70 with perforated by-pass holes 74 and slidingly engaging that engage a second set of tab portions 72 .

摘要： 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.

摘要： A rotary valve, a piston pump rotary valve assembly and a piston pump rotary valve assembly tank dispenser for use in discharging a metered amount of liquid, gel, or slurry has a valve body having a first channel pathway and a second channel pathway. The first channel pathway has an inlet opening to receive a liquid, gel, or slurry and an outlet opening to provide the same to a pathway of the piston pump assembly. The second channel pathway is segregated from the first channel pathway and includes a plurality of inlet openings, each capable of communicative alignment with the pathway of the piston pump assembly, and at least one outlet opening communicative with such inlet openings. The valve body is capable of rotation with respect to the piston pump assembly to dispose both the first channel pathway and the second channel pathway each to two operative positions to receive the liquid, gel, or slurry and to two inoperative positions blocking fluid communication with the liquid, gel, or slurry.

摘要： A piston pump comprising at least one working space, which is surrounded by a cylinder and which is adapted to be varied by a piston arranged in said cylinder, and at least one inlet valve as well as at least one outlet valve, said valves being lifting valves and being adapted to be controlled and driven by a control and drive means. In order to provide a piston pump which can be cleaned more easily and which includes the smallest possible number of dead spots, a first teaching according to the present invention suggests that, when closed, the inlet valve should be located nearer to the working space than when it is open. Alternatively, the underlying technical problem is solved according to a second solution of the present invention by the feature that the valve surface of the inlet and/or outlet valve(s) facing the working space merges without any steps with the inner surface of said working space at the closed position of the valve or of each valve.

摘要： It is an object of the present invention to provide a fluid suction and discharge apparatus capable of continuously discharging fluid with a predetermined flow rate and pressure continuously sucking the fluid without substantially giving rise to pulsation. This invention comprises an inner tube rotatably fitted in a fitting hole of the apparatus body, a cylinder slidably fitted into the inner tube, and a plurality of through-holes formed in the inner tube, wherein when the cylinder is reciprocated in association with rotation of the inner tube, and when one of the through-holes of the inner tube is communicated with a suction hole of the apparatus body, the other through-hole of the inner tube is communicated with a discharge hole of the apparatus body, and when fluid is sucked from a communication suction hole thus communicated, fluid is discharged from the discharge hole thus communicated.

摘要： A variable-delivery high-pressure fuel pump having a pump chamber varying in volume as a plunger moves in and out, an inlet port valve forming a part of chamber walls of the pump chamber, the inlet port valve being opened when a low-pressure fuel is admitted into the pump chamber, while being closed when the admitted fuel is delivered out of the pump chamber, a control chamber on an opposing end of the inlet port valve to receive the low-pressure fuel from the fuel inlet passage, and a control valve for intermittently opening and blocking a fluid communication between the control chamber and the fuel inlet passage. The inlet port valve is a poppet valve made with a valve head having a valve face moving off and reseating against a valve seat in the pump chamber, and a valve stem integral with the valve head and extending out of the pump chamber into the control chamber.
