Patent number: 5225641Abstract: 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).Type: GrantFiled: June 24, 1992Date of Patent: July 6, 1993Assignee: Allied-Signal Inc.Inventors: Rodney C. Weld, Richard A. Zander

Patent number: 5142965Abstract: 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).Type: GrantFiled: August 28, 1991Date of Patent: September 1, 1992Assignee: Allied-Signal Inc.Inventor: Richard A.

Patent number: 5046313Abstract: A master cylinder (12) having a switch (70) which is activated by either a magnet (78) carried by a float (76) in a reservoir (40) or a pin (66) moved by a differential area piston (52). The switch (70) had a first blade (82) connected a source of electrical current (106) through an indicator light (124) and a second blade (88) connected to an electrical ground (114). A reed switch (100) is connected to the first (82) and second (88) blades and responds to the magnet to close an electrical circuit to operate the indicator light (124) if a low fluid level is present in the reservoir (40). A first contact (96) on the first blade (82) is positioned in switch 70 by a non-electrical conductive actuation pin (66) that extends through the housing (22) of the master cylinder (12).Type: GrantFiled: July 27, 1989Date of Patent: September 10, 1991Assignee: Allied-Signal Inc.Inventors: Donald A. Crumb, William F. Dillon, Jr., Robert F. Gaiser, Richard A. Zander

Patent number: 5016442Abstract: 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.Type: GrantFiled: July 27, 1989Date of Patent: May 21, 1991Assignee: Allied-Signal Inc.Inventors: Richard A. Zander, Robert F. Gaiser, Donald A. Crumb

Patent number: 4995676Abstract: 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.Type: GrantFiled: December 8, 1989Date of Patent: February 26, 1991Assignee: Allied-Signal Inc.Inventors: Donald A. Crumb, Richard A. Zander, Robert F. Gaiser

Patent number: 4929033Abstract: The proportioning valve assembly (40, 140) may be screwed into a complementary-shaped opening in a master cylinder (10). The valve assembly (40, 140) includes a differential area piston (50, 150) biased by a spring (70, 170) toward the outlet (21, 121) which communicates with the rear brakes. The master cylinder (10) includes a pair of passageways (16, 18) which communicate primary fluid pressure and secondary fluid pressure directly to the differential area piston (50, 150) of the proportioning valve assembly (40, 140) to displace the piston (50, 150) to a balanced position. If there is a failure of pressure in the primary brake circuit, the proportioning valve assembly (40, 140) actuates the differential area piston (50, 150) to permit fluid flow to bypass the piston (50, 150) and be communicated directly to the rear brakes of the vehicle.Type: GrantFiled: November 3, 1988Date of Patent: May 29, 1990Assignee: Allied-Signal Inc.Inventors: Richard A. Zander, Robert F. Gaiser, William F. Dillon, Jr., Donald A. Crumb

Patent number: 4903387Abstract: 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).
