Definitions

  • FIG. I there is shown a pump indicated generally at 10 and comprising a housing 11 providing a flat end surface 12.
  • a drawn steel shell 13 is of generally cupshaped configuration and has an end wall 14 and side walls 16 terminating in an end flange 17 provided with an internal recess 18.
  • the shell 13 fits over the housing 11 and a locking ring 19 seated in the groove 18 engages the housing as at 20, thereby to lock the same in assembly with one another.
  • the elements of the cartridge pack are retained in alignment by means of dowel pins of special construction.
  • a dowel pin 40 which constitutes a hollow tube, thereby to provide an axially extending passage P3 through the interior thereof.
  • a ball 41 seals the open end of the dowel pin 40, but there is formed an orifice O2 in the wall of the dowel pin, thereby communicating the passage P3 with the cavity C2.
  • FIGS. 6, 7 and 8 the structure of the pump is disclosed in somewhat more detailed fashion. However, since most of the elements correspond in structural configuration and function, like reference numerals will be used to identify like parts.
  • a pump shown generally at 10 comprising a housing 11 providing a flat end surface 12.
  • a drawn steel shell is again indicated generally at 13 and has an end wall 14 and side walls 16 which terminate in an end flange 17 forming an internal groove 18 in which is seated a locking ring 19 engaging an adjoining portion of the housing 11.
  • a cartridge pack containing an axial row of pump components including a lower pressure plate Lp, a cam ring Cr and an upper pressure plate which is generally designated at Up but which may have bonded together parts forming a sealing face 30 and a backing plate 34 and a motive surface 36.
  • An Oring 32 is received in the outer portions of the upper pressure plate Up in a recess 31, thereby to sealingly separate an inlet portion 33 surrounding the cartridge pack and an outlet cavity C2 behind the pressure plate Up.
  • a compression spring 37 is disposed between the wall 14 and the upper pressure plate Up to provide initial cartridge loading and biasing force.
  • a stud has a head 71 internally of the shell wall 14 and a threaded portion 72 extends outwardly for mounting purposes.
  • the control spool 120 has a front land 124 slidably engaging the sleeve 111 inwardly of the O-ring seal 112.
  • a seat insert 126 is formed with a passage 127 leading to a pump outlet 128 and also has a throat 129 at one end forming a sized opening.
  • the control spool 120 has a valve head 130 which seats against the edges of the throat 129 thereby closing the sized opening and has a stem 131 projecting through the opening.
  • the stem 131 is tapered as at 132 and has a sense opening 133 formed in the end wall.
