Abstract: A hydraulic axial piston pump comprising a cylinder block closed at sides by a head and by a containment casing for piston actuating a plate, an electric motor coupled to the plate, reversible locking means for a bypass valve inserted in a seat of the body and kinematically connected to a microswitch connected to the electric motor, the reversible locking means comprising a retention element insertable transversely to the seat in a receptacle formed in the body without structure discontinuity, the bypass valve head being integrated in a shell external to the body and enclosing the microswitch and the kinematic system.

Abstract: A pump comprises a plurality of pistons movable in a direction, a swash plate arrangement forming an angle with said direction so as to reciprocate said plurality of pistons in said direction and an elastic element interacting with said swash plate arrangement to enable said angle to be modified. Between said elastic element and said swash plate arrangement a transmission device is interposed for receiving a force from said swash plate arrangement and transmitting a fraction of said force to said elastic element.

Abstract: A hydraulic axial piston pump driven by an electric motor, comprising an outer casing that is formed monolithically with elements for fixing the casing to the stator assembly of the electric motor; the electric motor being thus coupled directly to the outer casing.

Abstract: An oscillating swash plate for an axial piston pump, comprising a rotating disk-like body with an annular seat inclined with respect to the rotation axis of the disk-like body and on which can be accommodated sliding elements for the heads of the axial pistons, a toothed circumferential portion monolithic with the body that is coaxial to the rotation axis and can be coupled kinematically to a gear of the pump, the pump being functionally connected to a motor.

Abstract: A motor pump for high-pressure washers having a structure of the type that comprises a rotating plate that is inclined with respect to its axis and on which at least two pistons push, the pistons being arranged parallel to the axis in radially spaced positions. The rotating plate is associated for joint rotation with a motorized support, which is arranged opposite the pistons and on which the plate can oscillate freely in order to vary its inclination, with respect to the rotation axis, between preset values that determine the axial movement of the pistons, elastic elements for contrasting the variations in inclination induced by the pistons being functionally interposed between the plate and the support.

Abstract: A wobble-plate pump including a mushroom-shaped inclined wobble plate which is keyed directly on supporting bearings and is suitable to alternately move axial pistons. The mushroom-shaped wobble plate is connected to a drive shaft by connection elements.
