摘要： In an hydraulic wobble pump having, a housing assembly which has first and second oppositely disposed outer ends, a wobble chamber and a power transmission chamber formed in said housing, a wobble shaft mounted for rotation in said housing and extending into said wobble and power transmission chambers, said wobble shaft having an inner end located in said wobble chamber, a power transmission gear removably mounted on said wobble shaft and located in said power transmission chamber, a plurality of pistons slidably mounted in cylinders formed in said housing and extending longitudinally from said wobble chamber to said first outer end of said housing at circumferentially spaced intervals about the periphery of a central portion of said housing, the improvement of; a service passage formed at said second end of said housing and opening into said power transmission chamber, said passage being proportioned to permit said power transmission gear to pass therethrough when being mounted on or removed from the wobble shaft when it is located in said power transmission chamber, a fluid inlet passage extending inwardly from said first outer end through said central portion of said housing and opening into said wobble chamber directly opposite said inner end of said wobble shaft to permit an anvil shaft to extend therethrough to provide a support which will support the wobble shaft when said power transmission gear is being mounted on wobble shaft when it is located in said housing. The hydraulic wobble pump has an inlet passage extending inwardly from one end thereof through the central portion of said housing and opening into said wobble chamber. The inlet passage being arranged to admit hydraulic fluid to said wobble chamber substantially centrally between said cylinders so as to be substantially uniformly distributed to each cylinder in use.

摘要： A variable displacement wobble plate type compressor is provided with an inclined plate (12) which is hinged to a rotor (10) fixed on a drive shaft (7) and supports a wobble plate (15). The inclined plate is formed with a central hole (124) for penetrarion on the drive shaft. The inner surface of the central hole partly contacts the outer surface of the drive shaft to restrict radial movement of the inclined plate while permitting the angle of the inclined plate to be varied.

摘要： In a pump of the axial-piston or related type, the oblique disc (6), the front surface (5) of which determines the length of the stroke of the pistons (3), comprises a rear surface (7) forming a sharp acute angle with the front surface (5) and co-operating with an oblique front surface (8) on a second oblique disc (9) driven for rotation by a drive member (11), the first disc (6) being rotationally connected to the second disc (9) through an elastic member (12) so as to be able to "give", when the reaction force from the pistons (3) increases due to increased output pressure, thus causing said front surface (5) to "tilt" closer to a radial orientation. With this arrangement, automatic displacement control is achieved in a simple and inexpensive manner. The invention also relates to a high-pressure cleaner comprising the pump.

摘要： A reciprocating piston pump (10) provides pulseless delivery of liquid. It is suitable for use in compact environments or for the delivery of small amounts of liquid. The pump includes two pistons (18, 48) with pumping chambers that are alternately connected to inflow and outflow lines through a control valve (100). The control valve moves between a first position in which inflow is directed to the first piston chamber and outflow to the second piston chamber, and a second position in which outflow is directed to the first piston chamber and inflow is directed to the second piston chamber. A rotating cam (80) moves the pistons of the pump and the control valve between their operating positions described above. The cam rotates around an axis that is parallel to the axis of movement of the piston pumps. A control surface is carried by and rotated by the cam in one embodiment.

摘要： A cylinder fixed, axial-type rotary piston pump comprises a drive shaft (1) provided with a drum-type flywheel (2) or (2') coaxially mounted thereon, said flywheel being provided on its inner circumferential surface with a continuous inclined groove (2a) or (2'a) which is arranged so as to form a cycle of complete sine curve in its development view, and piston rods (8) connected to pistons (7) housed in cylinders (6), respectively, said piston rods being each engaged at its one end with said groove in a sliding manner, so that the pistons (7) are reciprocated by the rotation of the drive shaft (1). According to this invention, a large-sized apparatus may be manufactured and the sliding surfaces between movable parts may be remarkably reduced. Furthermore, this kind of pump may be operated with working fluids, for example, water rather than oil.

摘要： An axial piston pump of high pressure type comprises a driving shaft (12), a piston (4), a cam driving mechanism (6, 7, 8, 14, 19) disposed between the driving shaft and the piston for converting the rotary motion of the driving shaft to a reciprocating motion of the piston. An inlet valve (18) is disposed to open and close in response to the movement of the piston and an outlet (29) for the medium being pumped is provided in the pump housing, enclosing the pump. The cam driving mechanism comprises two cam pieces (6, 19). One of said cam pieces (19) is attached in a non-rotary way to the end of the driving shaft facing the piston and the other cam piece (6) is fastened to the end of the piston facing the driving shaft. The surfaces facing each other of the two cam pieces present cam surfaces (7, 14), designed to form axial roll cams in a circular race for a ball (8) disposed between said cam pieces.

摘要： In a hydraulic machine, especially a high-pressure hydraulic pump with pistons (5) driven by a wobble rotor (8), the angle (14) between the axis of any one roller (13) in the rotor bearing (11, 12, 13) and the axis (3) of the machine's drive shaft (4) is of the order of 30 to 60 angular degrees, preferably of the order of 40 to 50 angular degrees (approximately 45 degrees in the example shown). The use of an angle (14) within the ranges mentioned causes a reduction of the bearing surface pressure on the roller races (11, 12), thus also making it possible to form one (12) of said races integral with the wobble rotor (8), and also to use cylindrical rollers (13) instead of the more costly conical ones normally used in such machines.

摘要： In a multi-cylinder (1) displacement pump with a wobble plate (7) driving the piston (5) and being driven by a rotating wobble rotor (8) with an inclined bearing surface (9), the wobble plate (7) "floats", being held in place solely by rounded ends (6) on the pistons (5) engaging a groove (17) in the wobble plate (7) and urging the latter against a thrust bearing (14, 15, 16) between the wobble plate (7) and the wobble rotor (8). The groove (17) has a slightly larger radius of curvature (20) than that (21) of the piston ends (6), thus allowing for the slight deviation between the circular groove (17) and the slightly elliptic locus of the piston ends (6). With this arrangement it is possible to use a single wobble plate (as distinct from individual slide pads for each piston) with no other means to keep it in place than the pistons with which it cooperates.
