ln practical operation, oil under pressure ia Supplied to the cup 61 through rlle condlliL im. ille plunger 69 moving downwardly until the valve 71, cooperating with the seat 64, closes the outlet or nipple 65. When pressure is reduced in the conduity 109, the plunger 69 resumes the position shown in Fi ure 2, the plunger then being full of oil. gllnder a greatly reduced pres sure, the oil in the plunger is forced dowrr wardly through the openings 80 in the plate 79, through the retarder T8 and through the openings 70 in the bottom of the plunger 69, a slow supply of oil being provided Ytor the nipple 65 and it. being possible to re ulate this supply to a ninety, by manipu ating the valve 66.

It may happen that the purt to be lubricated, or some portion of the oil elianuel therein, or perhaps the bore of the nipple 65, may be elo ged. Under such Giri-uur stances. oil un er pressure is fed into the cup Gl. through the conduit 109. until the art 69 moves downwardly. the, spring 82 einer compressed, and the vulve 71 cooperet` ing with the seat 64 to prevent oil from passing into the nipple 65 due to uessure exerted on the retarder 7 8. Then. tlie presA sure of oil Within the cup (l1 builds up. and ultimately the spring T7 yields suddenly. it` being recalled that this sprint is sbonger than the spring 82.

tion, under the increased oil pressure und u charge of oil is shot. almost with en er-Y plosive force. through the bore ot the hollo'uI valve 1 (which is seated). und through the nipple 65. any ohstruetiou in the path ol the advunsring oil being swept away.

ln the modification delineuted in Figure 4, parts'hereiubetore described hure been deslgnated b v numerals previouslvv used. with the suflix u"'. The modilieution von siste in omittingr the valve G6 of `Figure In Figure 5. the oil eup is denoted ,etenv erally by the numeral 111 and includes u bod).y 112 carrying a eup 119 with whirl; the oil pressure pipe 120 is assembled, The body 112 of the oil rup iuehule4 a buse lll provided with a seat 11?. the. huso huvirrgr ou outlet or nipple 11V.

An inverted vup-shuped plunger 121 is Ymounted for reeiprovutiou in the hotly 112 und is rovided in its. hotlom with outlets 122. T e plunger or valve u'imnher 121 inoludes a hollow element or vulve 123 udupted to eoaet with the seul', 115. 3A retarder 121 is dis osed in the plunger 121 and is of the sort. iereinhefore deserihed. a cover pluto 125 resting on the retai'tler und having oper 'ings 126. the retainer for the @over plato being marked h v the numeral 12T. A rouipression spring 128 is interposed lvoueeil the bottom of the plunger 121 and the huso lVhen t le spring TT` yields. the valve T6 moves to an open posi- 114 of the eup hotly and tends to thrust the plunger 121 upwardlyv into Contact with the tup 1.19.

in raetioal operation. oil under pressure 1s delivered through the conduit 12D und the plunger 121 moves downwardly. thu spring 128 being compressed. the volw 1.22', coactiner with the seat 11T. und the cup being filled with oil. Upon a diminution of pressure, the plunger 121 moves to the position shown in Figure 5, under the :ution 0l the spring 128. the valve 123 being opened with respect to the seat 115. aud, thereu 0n, under a greatly reduced pressure, oil tous slowly through the openings 126 of the plate 125. through the retarder 121. through the openings 122 in the oase of the plunger 121, und into the nipple 11G.

The form shown in Figure 6 of the drawings is constructed like the form shown in liigure 5, saving` for the 'tact that valve 11T of Figure 5 is omitted. The form depicted in Figure G may. with u brief catalogue. of parte, the oil cup being denoted generally by the numeral 129 and including u body 130, u hase 131 having u seat 132.y the hose being supplied with u nipple or outlet` 133.
