Multiple use hand operated piston pump

Abstract

The multiple use hand operated pump consists of a rhomboid head ( 1 ), a mountable curve shaped outlet part ( 3 ), a pumping pipe part ( 2 ) with a special base ( 9 ) bearing valve ( 12 ) and a liquid inlet ( 13 ). A piston ( 4 ) with external grip ( 5 a ) on its upper end and an especially constructed valve ( 5,6,7,8 ) on its lower end, as well as a tapered component ( 14 ) constituting means of supporting, stablelising and mounting of the pipe part ( 2 ) of the pump on any liquid container.

1 .- Multiple use hand operated piston pump, characterised in that it consists of a main part with a rhomboid head ( 1 ), a mountable curve shaped outlet part ( 3 ), a pumping pipe part ( 2 ) with a special base ( 9 ) bearing a valve ( 12 ) and a liquid inlet point ( 13 ). A piston ( 4 ) with external grip ( 5   a ) on its upper end and an especially constructed valve ( 5 , 6 , 7 , 8 ) on its lower end, as well as a tapered component ( 14 ) constituting a means of supporting, stablelising and mounting of the pipe part ( 2 ) of the pump on any liquid container mouth.  
     
     
         2 .- Multiple use hand operated piston pump, as in  claim 1 , characterised in that the special base ( 9 ) bears an especially formed housing of the pumping pipe ( 2 ), said housing formed by an internal projection ( 10 ) and an external projection ( 11 ), so as to be fixed at the lower end of said pipe part ( 2 ), whereas the valve ( 12 ) which is being fixed at the liquid inlet point ( 13 ) has an opening-closing possibility.  
     
     
         3 .- Multiple use hand operated piston pump, as in claims  1  an  2 , characterised in that the especially constructed valve that it bears at the lower end of the piston ( 4 ) consists of a main part-plastic membrane ( 8 ), an auxilliary mounting ring ( 7 ), an upper valve lock support. ( 5 ) and a lower valve lock support ( 6 ).  
     
     
         4 .- Multiple use hand operated piston pump, as in claims  1 ,  2  and  3 , characterised in that the rhomboid head ( 1 ) bears an opening ( 1   a ) for the insertion and operation of the piston ( 4 ), said opening having such a diameter so that there exists a little gap, allowing air escape with this resulting to storage, additional feeding and directing of the liquid from said rhomboid compartment ( 1 ) towards the outlet point ( 3 ) during continuous pumping.  
     
     
         5 .- Multiple use hand operated piston pump, as in claims  1 ,  2 ,  3  and  4 , characterised in that the tapered component ( 14 ) is a supporting, stablelising and mounting means of the pumping pipe ( 2 ), with these being achieved with rings ( 15 ) that give the possibility of supporting and mounting of the pump on liquid containers having different diameter dimensions, whereas the guide ( 16 ) allows increase-decrease of the immersed into the liquid pipe part ( 2 ) as well as the stablelising of the pump at the right place.  
     
     
         6 .- Multiple use hand operated piston pump, as in claims  1 ,  2 ,  3 ,  4  and  5 , characterised in that its use can be widened for cleaning of garden ponds, swimming pools, fountains i sewage etc., by adding a dirt retaining filter ( 17 ) at the outlet point ( 3 ) or alternativelly for other uses, such as pumping from inside of boats or sea vessel engines, the transfer of liquid from one steady fixed container to another spaced apart steady fixed container etc, by adding of an oblong flexible piece of pipe.  
     
     
         7 .- Multiple use hand operated piston pump, as in claims  1 ,  2 ,  3 ,  4 ,  5 ,  6  and  7 , characterised in that the rhomboid head, in combination with the opening ( 1   a ) and the outlet point ( 3 ) create an open circuit assuring a much greater and faster pumping possibility due to retaining and storage of a signigicant amount of liquid within said romboid compartment ( 1 ) which finally feeds with extra liquid the outlet point ( 3 ) during the reciprocating movement process of the piston ( 4 ), resulting to the multiple rise adcantage of the pump.  
     
     
         8 .- Multiple use hand operated piston pump, as in claims  1 ,  2 ,  3 ,  4 ,  5 ,  6 , and  7 , characterised in that the valve system ( 5 , 6 , 7 , 8 ), piston ( 4 ) and base valve ( 9 , 10 , 11 ,  12 , 13 ), which could be characterised as a composite operation system ensures pumping, as follows:  
       During the first pulling action of the piston ( 4 ) in an upwards direction, the air from the points ( 1   a  and  3 ) contained in the romboid head ( 1 ) is removed, with this resulting to simultaneous liquid inlet through the flap valve ( 12 ) of the base. With continuing reciprocating movement of piston ( 4 ), pumping process is thereon achieved in an mechanical way by means of the valve ( 5 , 6 , 7 ,  8 ) of the piston ( 4 ), which tranfers the liquid towards the outlet point, through the romboid head ( 1 ), that finally comes out of the outlet mouth ( 3 ).  
     
     
         9 .- Multiple use hand operated piston pump, as in claims  1 ,  2 ,  3 ,  4 ,  5 ,  6 , 7 , and  8 , characterised in that it may be constructed in any total or partial dimensions of the components constituting it—height, diameters etc.—according to requirements of use each time  
     
     
         10 .- Multiple use hand operated piston pump, as in claims  1 ,  2 ,  3 ,  4 ,  5 ,  6 ,  7 ,  8  and  9 , characterised in that the shape, design and dimensions of the tapered component ( 14 ) may be altered, in order that there will be the posibillity of mounting and stablelising of the pump in any container of different height and capacity as well as of different shape of mouth containers.
