Claims (5)

1. Hydraulisk frem- og tilbakegående anordning (10), om-fattende et hus (12, 14, 16, 18) og i huset et stempel (20, 22) med en første stempelflate (26) og en andre stempelflate (28) , karakterisert ved at den har en innretning (30,32) som skaper intermittent forbindelse mellom den første stempelflate og det hydrauliske fluidum og en innretning (4 2) som kontinuerlig skaper forbindelse mellom den annen stempelflate og fluidum under trykk, idet stemplet beveger seg i en første retning (A) når det hydrauliske fluidum har forbindelse til den første stempelflate mens stemplet beveger seg i en andre retning (B) når det hydrauliske fluidum ikke har forbindelse med den første stempelflate.1. Hydraulic reciprocating device (10), comprising a housing (12, 14, 16, 18) and in the housing a piston (20, 22) with a first piston surface (26) and a second piston surface (28) , characterized in that it has a device (30,32) which creates an intermittent connection between the first piston surface and the hydraulic fluid and a device (4 2) which continuously creates a connection between the second piston surface and fluid under pressure, as the piston moves in a first direction (A) when the hydraulic fluid is connected to the first piston surface while the piston moves in a second direction (B) when the hydraulic fluid is not connected to the first piston surface. 2. Hydraulisk frem- og tilbakegående anordning (10) som angitt i krav 1, karakterisert ved at stemplet består av et første stempel (20) med den nevnte første stempelflate (26) og et andre stempel (22) med en andre stempelflate (28) .2. Hydraulic reciprocating device (10) as stated in claim 1, characterized in that the piston consists of a first piston (20) with the aforementioned first piston surface (26) and a second piston (22) with a second piston surface (28) ). 3. Hydraulisk frem- og tilbakegående anordning som angitt i krav 1, karakterisert ved at den hydrauliske frem- og tilbakegående anordning er en hydraulisk bormaskin.3. Hydraulic reciprocating device as stated in claim 1, characterized in that the hydraulic reciprocating device is a hydraulic drilling machine. 4. Hydraulisk frem- og tilbakegående anordning som angitt i krav 3, karakterisert ved at den har en slagborkrone (46) og ved at den annen stempelflate (28) slår mot borkronen når stemplet beveger seg i en første retning.4. Hydraulic reciprocating device as stated in claim 3, characterized in that it has an impact drill bit (46) and in that the second piston surface (28) hits the drill bit when the piston moves in a first direction. 5. Hydraulisk frem- og tilbakegående anordning som angitt i krav 1, karakterisert ved at innretningen (30,32) som skaper intermittent forbindelse mellom den første stempelflate og det hydrauliske fluidum er en roterende ventil (30) som setter den første stempelflate intermittent i forbindelse med en hydraulisk fluidumkilde (34) og med en hydrauliske returledning (36).5. Hydraulic reciprocating device as stated in claim 1, characterized in that the device (30,32) which creates intermittent connection between the first piston surface and the hydraulic fluid is a rotary valve (30) which intermittently connects the first piston surface with a hydraulic fluid source (34) and with a hydraulic return line (36).
