    摘要: An apparatus for pumping a fluid from a fluid inlet (90;92) to a fluid outlet (92;90) is disclosed. The apparatus comprises:
    a spool (14) axially movable within a cavity (40), wherein a first chamber (42) is located at a first axial end (46) of the cavity (40) and a second chamber (44) is located at a second axial end (48) of the cavity (40), wherein the volume of the first chamber (42) and the second chamber (44) varies depending upon the axial position of the spool (14) within the cavity (40);
    a valve (52) movable between a first position and a second position, wherein in the first position the valve (52) is configured to convey fluid from the fluid inlet (90;92) to the first chamber (42) and from the second chamber (44) to the fluid outlet (92;90), and in the second position the valve (52) is configured to convey fluid from the fluid inlet (90;92) to the second chamber (44) and from the first chamber (42) to the fluid outlet (92;90); and
    a control system configured to control the movement of the spool (14) and the valve (52).

    摘要: To provide a pump device for lubricant which is downsized and reduced in cost due to a simplified decompression structure. A pump device S for lubricant comprising a pump main body 10 which is provided with a cylinder part 15 which suctions lubricant stored in a tank and discharges it from a discharge port 13 and a piston 30 and an actuator 40 which allows the piston 30 to move forward and backward, in which when lubricant is supplied to a lubrication pipeline W connected to the discharge port 13, the discharge port 13 is compressed, and when the supply of lubricant to the lubrication pipeline is stopped, the discharge port 13 is decompressed, wherein the piston 30 is allowed to move forward to the 1 st position P1 at which lubricant is discharged, move backward from the 1 st position to the 2 nd position P2 at which lubricant is suctioned and further move backward from the 2 nd position to the 3 rd position P3, and a decompression path 50 which is blocked when the piston is allowed to move between the 1 st position P1 and the 2 nd position P2, and is opened when the piston is moved backward to the 3 rd position is formed in the pump main body 10.

    摘要: La présente invention concerne un dispositif de liquéfaction hydrothermale d'une composition à base de biomasse, comprenant :
    - une enceinte définissant un volume V E , comprenant trois zones successives Z1, Z2 et Z3 :
    la zone Z1 étant munie d'une entrée E Z1 d'une composition à base de biomasse, et étant à une température T Z1 et à une pression P Z1 ,
    la zone Z2 correspondant à une zone de réaction par liquéfaction hydrothermale de la biomasse à une température T Z2 et à une pression P Z2 ,
    la zone Z3 étant munie d'une sortie S Z3 des produits issus de la réaction par liquéfaction hydrothermale de la biomasse, et étant à une température T Z3 et à une pression P 73 ,

    - deux pistons P1 et P2, coulissant indépendamment l'un de l'autre entre les zones Z1, Z2 et Z3 de manière à amener la composition à base de biomasse de la zone Z1 vers la zone Z3, les pistons P1 et P2 étant susceptibles d'être espacés l'un de l'autre de manière à définir un volume V P variable et inférieur à V E ,
    - un moyen de chauffe externe de la zone Z2,
    - des moyens d'activation des pistons P1 et P2 permettant de faire varier le volume V P .

    摘要: The present application relates to a pump unit (1) for a fuel injection system. The pump unit (1) has a low pressure fuel supply line (11) and a high pressure fuel outlet (13). A pumping chamber (5) having a plunger (15) is operable to perform a pumping cycle comprising a pumping stroke and a filling stroke. The pump unit (1) also includes an inlet valve (7) having an inlet valve member (19) movable between an open position for permitting the supply of fuel to the pumping chamber (5) from the low pressure fuel supply line (11) and a closed position for inhibiting the supply of fuel from the pumping chamber (5) to the low pressure supply line (11). An outlet valve (9) is provided in the high pressure fuel outlet (13). The pump unit (1) also includes means (39) for coupling the plunger (15) to the inlet valve member (19). The present application also relates to a method of operating a pump unit (1).
