摘要: A volumetric pump comprises at least one piston (1) inside a cylindrical housing (2) and means to cause a relative to-and-fro linear movement between the cylindrical housing (2) and the piston (1) in order to produce a stroke of the volumetric pump. This pump further comprises a bi-directional angular rotatable disc (4) acting as a valve which connects alternately at least one inlet port and at least one outlet port (5, 5') to a least one pump chamber (6, 6') located inside the housing (2), and a driving mechanism arranged to dissociate at least partially the bi-directional angular movement of the rotatable disc (4) with the to-and-fro linear movement of the housing (2). This driving mechanism is arranged such that the rotatable disc (4) reaches an angular position at which it opens and/or closes the inlet and/or outlet ports (5, 5') when there is no relative to-and-fro linear movement between the cylindrical housing (2) and the piston (1).

摘要: A volumetric pump (1) comprising at least one piston (2) in a hollow cylinder (3), said pump (1) having at least one inlet port (10) through which a liquid (15) can be sucked into a pump chamber (3) during an instroke of said piston (2), and at least one outlet port (11) through which the liquid (15) can be expelled during an outstroke of the piston (2). Said piston (2) or the hollow cylinder (3) of the volumetric pump (1) can be actuated directly or indirectly by at least one rotor (5). This rotor (5) transmits, on the one hand a bi-directional linear movement to the piston (2) or to the cylinder (3) causing said piston (2) to slide back and forth inside said cylinder (3) or following the axis of said piston (2), and on the other hand, a bi-directional angular movement either to the piston (2) or to a disc (24) in order to open and close alternately the inlet and outlet ports (10, 11).

摘要: A pump system for producing high and exactly controllable pressure levels includes a piston pump which has a piston (32) connecting to a spindle shaft (22), a spindle nut (44) on said spindle shaft, a cylinder block (34) having a bore (36) for receiving said piston, a mechanism (14, 16, 26) for imparting relative rotational and axial motions between said piston and said cylinder block including a device for causing relative rotary motion of said spindle and spindle nut. A helical spring (46) or other resilient element is connected between said cylinder block (34) and said spindle nut (44) to compensate the reaction force generated by a pressurized fluid sample in said cylinder bore (36) when put under compression. A flexible element (30) is connected between the piston (32) and the spindle shaft (22) to compensate for any axial misalignment of the piston and the cylinder bore. Methods for operating such a system under adiabatic, isothermal, isobaric and isochoric conditions are described.

摘要: The compressor includes a cylindrical housing (1), in the bore of which moves a piston (3) whose periphery is adjusted with little play in the cylinder (1). The end (5) of the piston (3) includes a gas inlet (6) and supports two spherical joints (7) as well as connecting rods (8, 8') which are symmetrical in relation to the axis of the piston (3). The connecting rods (8, 8') pass with play through a transverse wall (11) of the housing (1) and are driven by a mechanical member (13), which includes a mobile component (14) having a rectilinear reciprocating movement, and by a compensator (15). The connecting rods (8, 8') are connected to the compensator (15) by means of ball joints (16, 16') and the compensator (15) is connected by a ball sorbet joint (17) to the mobile component (14). Application: in the manufacture of piston-cylinder machines, in which the piston is driven in a relative reciprocating movement without radial load transmission.

摘要: A two-component pumping system includes a first pump for pumping a first component, a second pump for pumping a second component, a motor, and a yoke assembly for connecting the motor to the first pump and the second pump and driving them simultaneously. The first pump includes a first displacement rod that reciprocates in a first pump axis. The second pump includes a second displacement rod that reciprocates in a second pump axis parallel to the first pump axis. The motor includes a drive shaft configured to reciprocate in a drive axis that is parallel to and in a common plane with the first and second pump axes. The motor is also configured to drive the first and second displacement rods in unison. The yoke assembly includes a top connector and a shoe. The top connector connects to the drive shaft.

摘要: The invention relates to a piston pump (10) for a slip-controlled, hydraulic vehicle brake system. The aim of the invention is to provide a piston pump (10) which comprises a short construction. To this end, a piston (16) of the piston pump (10) is configured as a hollow piston whose interior forms a compression chamber (42) of the piston pump (10). The piston can be economically manufactured as a shaped part, for example, by deep-drawing.

摘要: The invention relates to a piston pump (10) for a hydraulic vehicle brake system having, in particular, slip-control. The invention provides that the piston (16) is configured as a hollow piston and is sealed by a piston sealing (28) which comprises a sealing lip, can be flown around in a direction toward the interior of the piston (compression chamber (26)), and which forms the one inlet valve of the piston pump (10). By virtue of the inventive piston pump, the provision of a separate inlet valve is no longer necessary while, at the same time, obtaining a piston pump (10) that comprises a short construction.
