Definitions

  • This invention relates to hydraulic brake systems and moreA particularly to a fluid kcompression device therefor.
  • An object of' this invention is to provide a compression device having a conventional compression cylinder and interchangeable heads so that the cylinder may be readily converted into a comzpound compression cylinder.
  • Another object of the invention is to provide a 10 iiuld compression device including a cylinder having interchangeable heads. 4
  • Another object of the invention is to provide a compression device including a cylinderA and means for converting the cylinder into a compound cylinder.
  • a further-object of the invention is to provide a fluid compression device comprising va cylinder and a head therefor including a sleeve received by the cylinder to provide a cylinder having two chambers of different diameters.
  • Yet a further object of the invention is to provide a iiuid compression device comprising a cylinder readily convertible to a large compression chamber and a small compression chamber.
  • Fig. 1 is a schematic illustration of a complete hydraulic brake installation including an improved iluid compression; device;
  • Fig. 2 is a vertical sectional view of a fluid compression device embodying the invention
  • Fig. 3 is a sectional view of a cylinder head
  • I8 represents a Vuid compression device including a reservoir I2 having 4o a filling opening I4 closed as by a plug I6 pro- 45 and the reservoir.
  • a cylinder 28.V Formed at the base of the reservoir is a cylinder 28.V This cylinder is open at both ends and has ports 22 and 24 providing communications between the cylinder inder 28 is closed as by a head 26 of a conventional vtype, such as is shown in Fig. 3.. Preferably the head is threaded in the cylinder.
  • This head has a sleeve 38 which extends into the cylinder 28 to provide a plurality of chambers 82 and 34.
  • the sleeve has a portion of small 1 i diameter which in conjunction with the wall of Generally one end ofthe cyl- ⁇ (Cl. Bil-54.6)
  • 5 'Ihe head 28 has a discharge port 48 controlled as by a valve 42, and threaded in the discharge port is a coupling 44 connecting a fluid pressure switch 46, and the switch is connected in a circuit 48 including a battery 68 and a lamp 62, the circuit being suitably grounded as indicatedat 64 and 56.
  • uid pressuredelivery pipes or conduits 58 and 68 connected respectively to corresponding pairs of uid pressure motors 62, one pair for actuating the brakes associated with the frontl wheels of a vehicle and the other for actuating the brakes associated with the rear wheels of the vehicle.
  • Each of the iluid pressure motors is connected between the separable ends of friction elements 64 and 66 for spreading these elements into drum engagement. As shown. each pair of friction elements is pivoted on a backing plate 68 associated with a rotatable drum 18 and the friction elements of each pair are connected to one another by a retractile spring 12.
  • a piston 14 reciprocable in the chambersv82 and 84 is held against displacement by a washer 16 supported on a retaining ring 18 tted in a circumferential groove in the wall of the cylinder adjacent the open end thereof.
  • the piston has a head 88 and a skirt 82 reduced in diameter to provide in conjunction with the wall of the cylinder 28 an annular chamber 84 communicating with .the reservoir I2 as by way of the port 22.
  • a plug 86 threaded in the skirt of the piston provides, in conjunction with the skirt, a chamber 88 having a port 98 providing a communication Ybetween the chamber 88 and the chamber 84.
  • the plug 86 has a groove for the reception of a leak-proof cup 92, and formed in the back of the plug is a recess 94 for the reception of one end of a thrust pin 96 the other end of which s suitably secured to a coupling 98 connected .as byY a boot
  • the coupling 98 is connected to one end of a rod
  • the head 80 of the piston has a plurality of ports or passages
  • the head 80 has formed thereon a concentric sleeve
  • 8 in its periphery to provide for disinterrupted iiow of fluid is seated on the inner end of the sleeve 30, and a spring
  • the sleeve 2 carries a head
  • This head has a plurality of ports
  • 2 ⁇ extends through the piston head
  • a portion of the piston 30 is reduced in cross section to form an annular passage
  • 30 carries a valve
  • the fluid passes through the valve 42., the port 40 and the coupling 44, and thence through delivery pipes o; conduits 58 and 60 to the fluid pressure motors Movement of the fluid under pressure through the coupling 44 results in actuation of the switch 46 to close the circuit 48. This results in lighting the signal lamp 52. Simultaneously therewith, the fluid, moving under pressure through the delivery pipes or conduits 58 and 60, causes actuation of the fluid pressure motors 62 to spread the friction elements 64 and 66 against the resistance of retractile springs 12 into engagement with the drums 10.
  • 34 opens the pressure on the fluid is transferred without loss from the piston head to the piston head
  • 30 has been reduced by relief of the pressure on the valve
  • high-pressure piston detachably secured to said tubular sleeve and located in the sleeve-like part of said cylinder head, said part having a port forward of the retractedposition of the highpressure piston, a plunger guided in said tubuf lar sleeve and having a relief valvel for the lowpressure cylinder, means for advancing said detachably connected pistons under applied lpressure, and a spring compressed between the lowpressure piston and cylinder head sleeve for re- 10 turning said pistons to retracted position.
