A pneumatic system for a medical fluid machine operating a medical fluid cassette, the pneumatic system including an interface for supplying positive pneumatic pressure and negative pneumatic pressure to the medical fluid cassette; a source of positive pneumatic pressure; a source of negative pneumatic pressure; and a pneumatic pump including a first head and a second head, wherein the first head is dedicated to supplying positive pneumatic pressure to the positive pneumatic pressure source and the second head is dedicated to supplying negative pneumatic pressure to the negative pneumatic pressure source.

The invention relates to a fluid flow device comprising a plurality of fluid flow functional modules each fastened on a respective individual base comprising: two parallel lateral faces via which the bases are adapted to be placed against one another in such a manner that when the bases are placed against one another, two of the bases each have one lateral face that is free; a primary fluid transport channel passing through the base to open out in its two lateral faces in identical positions; and a front face along which the module extends so as to couple an inlet channel of said module with a secondary channel extending in the base from the front face and opening out in the primary channel.

According to the invention, the device includes fastener means for fastening the bases to one another and leaktight coupling means for coupling the end of the primary channel opening out in one of the lateral faces to a source of fluid under pressure for feeding the modules.

A fastening bolt fixes a plurality of stacked plates on each of which a hydraulic integrated circuit for hydraulically controlling an automatic transmission or a continuously variable transmission is formed. The fastening bolt includes a communication passage that communicates between the hydraulic integrated circuits among the plurality of plates.

Methods and apparatus to couple manifold blocks to form a manifold are disclosed. An example apparatus includes a first manifold block including a first fluid passageway defining a first opening in a first surface of the first manifold block. The example apparatus includes a first keyway extending along the first surface of the first manifold block. The example apparatus includes a first key to be inserted in the first keyway and a second keyway of a second manifold block to couple the first manifold block to the second manifold block to fluidly couple the first fluid passageway to a second fluid passageway of the second manifold block.

An object of the present invention is to improve assembling workability of the flow passage block and the sealability between the manifold solenoid valve and the flow passage block. A flow passage block 61 is mounted on a manifold solenoid valve having valve bases 12 on which solenoid valves 11 are respectively mounted, a block mounting face 60 is formed by the valve bases 12, an output joint 36 protrudes from each valve base, a joint seal member 71 is detachably mounted on the output joint 36, with the flow passage block 61 being mounted on the block mounting face 60, the joint seal member 71 seals between an outer peripheral surface of an output joint 36 and an inner peripheral surface of an connecting hole 64 which communicates with an air passage of the flow passage block 61.

A food article defect removal apparatus includes a manifold that defines one or more chambers for holding pressurized fluid. First channels extend from a first side of the manifold into fluid communication with the chambers. Second channels extend from the first side of the manifold to a second side of the manifold. Valves selectively connect corresponding first channels and second channels together to dispense the pressurized fluid from the manifold. The manifold can have an exterior wall that at least partially defines a first chamber and a second chamber, with an interior wall disposed between the first chamber and the second chamber. The interior wall can define the second channels. The valves can be included with a valve assembly, which includes a driver operably coupled with the valves. The valves can be pluggably coupled with the driver.

A protruding section formed at the one side end of a connector section provided in a valve is inserted into a recessed section formed as part of a valve placement section of a fluid apparatus. The valve is caused to pivot with the inserted portion that serves as a supporting point, and an engaging section formed at the front end of a lever of a hook section formed at the other side end of the connector section is allowed to engage with an engaging protruding section formed as part of the valve placement section of the fluid apparatus. The valve is thus attached to the fluid apparatus.

A multi-control valve device includes: a valve block including a plurality of valve holes; a plurality of spools movably housed in the plurality of valve holes in a one-to-one correspondence; one or more attachment parts provided on the valve block; and a plurality of solenoid valves provided on the one or more attachment parts in a one-to-one correspondence with the plurality of spools and each of which reduces a primary pressure, outputs a secondary pressure to a corresponding one of the plurality of spools, and moves the spool. The valve block includes a primary pressure supply passage through which the primary pressure is supplied to each of the plurality of solenoid valves.
