摘要： The positioning ring (44) for a hydraulically operated warning device (80) may be utilized for any hydraulically movable piston or sleeve (52) which, when properly assembled, causes a warning device (80) to effect an initial mode of response. The positioning ring (44) has a reduced inner diameter portion (41) separated from an enlarged inner diameter portion (43) by way of a radial shoulder (42). The enlarged inner diameter portion (43) abuts a shoulder (17) of a surrounding housing (11) and the radial shoulder (42) abuts a shoulder (59) of the piston or sleeve (52). The housing (11) may contain a warning device (80) which engages the piston or sleeve (52) such that if the piston or sleeve (52) is displaced in an axial direction the warning device (80) is operated. Should the centering ring (44) be mis-assembled or not included in the assembly, either the misassembled positioning ring (44) or the lack of the positioning ring ( 44) permits the piston or sleeve (52) to be moved to a position where the warning device (80) is operated to provide an indication that the positioning ring (44) is either misassembled or missing from the assembly.

摘要： The unitary poppet valve assembly (50) comprises an annular retainer (52) having an open end (54) and an opposite end (55) with a small diameter opening (56) therein. The annular retainer (52) has a plurality of fingers (58) extending laterally therefrom for engagement with the body (12) of a proportioning valve assembly (10). A poppet (70) comprises a poppet head (72) extending radially outwardly from a longitudinal shaft (74), and an oppositely disposed abutment (76). The shaft (74) extends slidably through the small diameter opening (56) in the annual retainer (52), the abutment (76) engaging the retainer (52) adjacent the opening (56). A spring (60) is disposed between a corner or shoulder (57) of the annular retainer (52) and a shoulder (77) defined between the poppet head (72) and poppet shaft (74). The poppet (70) includes a central through opening (78) extending through the abutment (76) and to the head (72), wherein the opening (78) communicates with a lateral through opening (80) of the shaft (74). The unitary poppet valve assembly (50) may be inserted directly within an inlet opening (13) of the proportioning valve assembly (10) so that the fingers (58) engage the body (12) of the proportioning valve assembly (10).

摘要： A cap for a reservoir of a master cylinder having a disc member with a plurality of perpendicular guides located on a fixed radius from the center of the disc member for aligning a cylindrical body secured thereto. The cylindrical body has an annular flange with a tapered peripheral surface thereon extending from an edge of a shoulder formed adjacent the annular flange. A diaphragm has an annular base connected to an apex section by a first conical leg and a center section connected to the apex section by a second conical leg. The diaphragm has a plurality of ribs that engage the disc member when an annular lip is located on a shoulder of the cylindrical body. When inwardly projecting tabs on the annular edge of the disc engage corresponding arcuate projections extending from the cylindrical neck to fix the cap to the reservoir, the tapered peripheral surface on the flange of the cylindrical member engage the first conical leg to provide a radial force which urges the first conical leg into engagement with the cylindrical neck of the reservoir to form the primary sealing for the reservoir while the plurality of ribs are compressed between the disc and and top of the cylindrical neck to from the secondary sealing for the reservoir.

摘要： A master cylinder having a housing with a first bore therein for retaining a pair of pistons which move in response to an input force and develop fluid pressure to effect a brake application. A second bore in the housing carries a differential area piston connected to the pressure chambers. A reed switch retained in the housing is aligned with a first magnet located on a float in a reservoir and a second magnet is attached to the differential area piston. A ferromagnetic shield located between the reed switch and second magnet has first and second openings located in a plane on either side of the reed switch. Should a failure occur in either pressure chamber, the differential area piston moves to allow magnetic field to pass through the openings in the shield and activate the reed switch to develop a warning signal and inform an operator of a failure mode condition in the master cylinder.

摘要： The flow switch assembly (10) of a fluid power apparatus comprises a fluid flow pressure operated switch (10) which activates upon the failure or degradation of fluid flow. A body (14) contains therein a blind bore (15) which receives a piston (71) biased by a spring (17) located at the bottom (13) of the bore (15). A switch housing (11) which is molded about a contact (20) is threadedly inserted into an open threaded end (16) of the bore (15). The bore (15) communicates with a fluid flow opening such that fluid pressure causes the piston (71) to retract against the spring (17). The contact (20) extends axially beyond a wall (11A) of the switch housing (11) such that a radially enlarged portion (21) provides a seat for a seal (30) which sealingly engages the radially enlarged portion (21) and a surface of the bore (15). If fluid flow should cease or fall below a predetermined pressure level, the piston (71) is displaced by the spring (17) and engages the contact (20) to complete a circuit and energize an electric motor pump which provides fluid pressure to the associated fluid power apparatus.

摘要： The master cylinder piston retaining member (90, 190) comprises either a flexible, ribbed bellows type member (190) or a nonflexible member (90) attached at one end of the master cylinder (10) in order to retain the primary piston (30) within the master cylinder (10). A cartridge master cylinder (10) having an end member (18) attached at one end (16) and retaining a sleeve member (20) within the bore (14), includes a pair of pistons (30, 40) with one piston (30) biased by a top hat construction (50) comprising one member (52) telescopically and slidable received within the other member (54) and having a spring (55) extending therebetween so that the maximum expansion of the spring (55) is limited. The primary piston (30) of the master cylinder (10) is positioned within an opening (26) of the end member (18). The piston retaining member (90, 190) is seated at one end within the end member (18) in order to be attached therewith and at the other end includes a radially inwardly extending flange (91, 191) which engages an axial end (31) of the primary piston (30) in order to limit by a predetermined amount the position of the primary piston (30) relative to the master cylinder (10). The piston retaining member (b 90, 190) enables a previously used top hat construction for the secondary piston (40) to be replaced with merely a spring (56).
