    摘要: A syringe pump which includes a pusher block is slidably mounted on bearings on one or more guide rails. The pusher block is advanced or retracted by a lead screw having an axis which is offset from the axis of the one or more guide rails which are supported at their respective ends by support blocks, wherein forward and/or trailing sides of the pusher block bearings are extended, and wherein the guide rail support blocks include recesses for accommodating the extended ends of the pusher block slide bearings. In another embodiment, the syringe pump includes quick connect-disconnect fixtures for loading and unloading syringes. Other mechanical, and programmable improvements are described in the specification.

    摘要: A pressure switch particularly adapted for use with high pressure fluid is shown having a frusto-conical support surface in the form of a protuberance (121, 121') formed at the center of a surface of a piston guide member (12, 12'). A stretchable diaphragm cap member (14, 14') generally in the shape of an inverted V is closely fitted on the protuberance (121, 121') of the piston guide member (12, 12') as well as the head (111b) of a piston member (111, 111') received in and projecting out of bore (120, 120'a) formed centrally through protuberance (121, 121'). The outer thickened peripheral berm (143, 14'a) of the cap member (14, 14') is inserted into a recess (102e, 102'e) in the wall defining an enlarged portion of the bore (102) which in turn opens to a cavity (103, 103') of the upper housing (10, 10') in which piston guide member (12, 12') is disposed. The cap member (14, 14') serves to seal the fluid passage side of the switch from the remainder of the switch. In several embodiments a ring (40, 400, 410) is placed between the cap member (14, 14') and the conical support surface (121, 121') to reduce sliding friction and to prevent extrusion of the cap member material into a gap formed between the piston member (111, 111') and the piston guide bore (120).
