    Abstract: A pump configured so that tools are not required to remove the pump head (12) and disassemble the plunger (30). A single large hand operated knob or head nut (60) facilitates tool-less pump head removal. The pump head is guided into position in a manifold (54) and held in place by the hand knob. The manifold is designed to receive all the external fluidic connections made to the pump head. Fluid paths to the pump head have been replaced with miniature face seals (56) which facilitate high pressure sealing between the pump head and manifold. Low pressure tubing seals reside in a seal wash chamber (50) or housing and are not attached to the head, eliminating the need for tooling to disconnect them during pump head removal. A tool-less plunger mechanism includes a nutcap assembly having a plunger socket receiving a plunger assembly including a sapphire plunger fixed to a plunger holder ball accommodated by the socket. The plunger assembly is captured within the socket by a plurality of cams. The cams are spring loaded to rotate and collapse onto the plunger holder ball (32) pulling the plunger assembly tightly into the socket. A restricting cone is actuated to rotate the cams away from the plunger holder ball for release and removal of the plunger assembly.

    Abstract: There is provided a high pressure fuel pump which includes a reliable fuel seal having a long durability and which can be produced at a relatively low cost. When a rotating shaft 4 is rotated to rotate a swash plate 7, such rotation is transmitted to a piston shoe guide plate 8 through a thrust ball bearing 9. Since the plate 8 is supported by a spherical portion 16 of a rod 14 mounted to a body 12, the plate 8 performs a precession to recurrently operate a plurality of fuel pumps 21 to 25 disposed around the rod 14. Each of the fuel pumps 21 to 25 includes a bellows provided between an outer end of the piston and the body 12, and the bellows completely seals a fuel leaked from a sliding clearance between the piston and the cylinder. Since the leaked fuel is introduced into a return passage 19 through a groove formed in an outer wall of the cylinder, a large internal pressure is not applied to the bellows and therefore, the bellows can be made of a low-priced material such as Teflon.

    Abstract: A swash plate type variable-capacity compressor (3) includes a piston (23) with a piston rod (53) and a piston driving mechanism, the piston driving mechanism comprising a drive shaft(5), a swash plate (59) inclined and hinged with the drive shaft (5) to be rotatable together with the drive shaft (5) but being swingable on the drive shaft (5), and sliding shoes (79, 81) coupling the swash plate (59) to the piston rod (51) so as to reciprocate the piston (23) by rotation of the swash plate (59). In the compressor (3), the swash plate (59) is made of a copper alloy. Preferably, the copper alloy is at least one alloy selected from the group consisting of a high-strength brass alloy, a bronze alloy, and a lead-bronze alloy.

    Abstract: Auf einer Kurbelwelle (2) ist in einem Kurbelgehäuse (1) auf einem Exzenter eine Pleuelstange (10) mit einem Pleuelschaft (11) gelagert. Der Pleuelschaft (11) ist hohlzylindrisch mit Innengewinde gestaltet und in ihn ist ein Pleuelkopf (12) mit einer Verlängerung (14) längenverstellbar eingeschraubt. Die Lage wird mit einer Kontermutter (18) gesichert. Der Pleuelkopf (12) hat eine Kugelkopfform und ist in einem zweiteiligen Kreuzkopf gelagert, wobei ein Hohlzylinder (23) und ein darin passender Druckbolzen (24) gemeinsam eine Lagerpfanne (25) für den kugelkopfförmigen Pleuelkopf bilden. Der Kreuzkopf (22) steht über eine Triebstange (33) und eine Kupplung (31) mit der Kolbenstange (32) einer cryogenen Kolbenpumpe in Verbindung. Diese Konstruktion nimmt Ungenauigkeiten in der Winkligkeit sowie die auftretende Parallaxität einwandfrei auf, so dass vom Kreuzkopf (22) bis und mit zur Kolbenstange (32) eine reine exakte axiale Bewegung stattfindet. Folglich treten kaum Querschübe auf, und der Verschleiss der Lager ist minim. Ferner ist eine exakte äusserst einfache Längeneinstellung der Pleuelstange möglich, womit die cryogene Pumpe immer optimal arbeiten kann.
