Title: Vacuum distributor unit for vehicle hydraulic brake systems
IPC: B60T13/24
Filed: 1962-09-13
Abstract: 1,007,378. Fluid-pressure brakes. P. MASSARDI. Sept. 13, 1962 [Sept. 14, 1961], No. 35008/62. Heading F2F. A vacuum servomotor for boosting pressure in an intermediate hydraulic cylinder 9 comprises an inlet 12 from a master cylinder, a valve assembly 13 controlled by the hydraulic pressure at the inlet 12 through a hydraulic piston 23 operating in a small diameter transverse bore connected by passage 12a with the inlet 12, the valve assembly controlling communication between a vacuum source connected to vacuum inlet 41 and a passage 42 leading to vacuum chamber 3 of an atmosphere suspended vacuum cylinder 1 having a piston 4, and between the passage 42 and atmosphere, and a hydraulic piston 8 in the cylinder 9 which is mechanically coupled to the piston 4 by a rod 6 and is provided with a seal 15 floating in a groove 14 so as to allow fluid to flow past the piston 8 via passages 16, 17, 52 when chamber 3 is open to atmosphere, but to close the passages 16 to prevent such flow when vacuum is communicated to chamber 3 and piston 4 is applying a thrust to piston 8 via the rod 6. The valve assembly comprises a stepped rod 31 positioned by compression springs 34, 35 acting in opposite directions on a flange of rod 31, the former being arranged between the flange and piston 23 and the latter between the flange and a sleeve 25 screwed into the housing 18. An exhaust valve 40 is fitted between a threaded collar 37, adjustable on a threaded portion of rod 31, and a securing nut, which valve cooperates with a seat 30 formed in a piston 27 which is normally held against a step 26 in the housing 18 by a spring 28. An inlet valve is slidable on rod 31 between the collar 37 and a shoulder of rod 31 and is normally held on a seat formed by the sleeve 25, owing to the vacuum at inlet 41. When hydraulic pressure at inlet 12 rises it is first communicated directly via the passages 16, 17, 52 to the hydraulic outlet 11, until pressure is sufficient to move piston 23 and cause rod 31 to move. This first closes valve 40 against seat 30 and moves piston 27 away from shoulder 26, then the shoulder engages valve 39 and moves it to communicate vacuum to the chamber 3 to actuate piston 4. As vacuum builds up in chamber 3 it acts on piston 27 to move it back towards shoulder 26 until valve 39 re-engages the seat in sleeve 25, thus lapping the valve assembly until hydraulic pressure at inlet 12 is either further increased, or reduced to cause chamber 3 to be reconnected to atmosphere.
