Patent number: 4806901Abstract: A device for transmitting linear motion into rotary motion, particularly as applied to an oil pressure transducer for a vehicle I.C.E. Specifically, the linear movement is produced by action of pressure against a diaphragm as opposed by a yieldable spring. The spring is a wire curved into a helix shape and with the ends attached to a rotary table. The midportion of the spring is operably attached to the central portion of the diaphragm so that linear movement thereof toward the rotary table causes the spring's end portions to progressively engage the table in overlying relation and, accordingly, to produce rotation of the table.Type: GrantFiled: August 21, 1986Date of Patent: February 21, 1989Assignee: Chrysler Motors CorporationInventor: Alfred H.

Patent number: 4086557Abstract: A variable resistance pressure transducer having high resolution, a wide resistance range and usable in conjunction with a limited linear actuation movement is provided. The transducer basically comprises a helical resistance element and a circular ring shaped contact arm which are mounted around a central axis and are slideably movable with respect to each other in directions parallel to the central axis. The ring contact essentially forms the wiper arm of a potentiometer assembly and the ring is dimensioned and positioned so that varying portions of its inner circumferential surface will contact the resistive element during relative linear axial movement between the ring and resistive element. This results in moving the effective point of contact between the ring and resistive element continously along the surface of the helical resistive element in response to the relative axial movement.Type: GrantFiled: May 6, 1976Date of Patent: April 25, 1978Assignee: Motorola, Inc.Inventors: Kenneth Warren Padgitt, Stanley Marion Kujawski
