摘要： The apply and release hydraulic parking valve (20, 120) comprises a housing (40, 140) having therein a bore (42) with first (52, 152) and second (54, 154) reservoir grooves communicating with one or more reservoir ports (46, 146A, 146B), a supply groove (63) communicating with a supply port (47, 147), and apply (44, 144) and release ports (48, 148) communicating with said bore (42, 142). A spool valve (60, 160) is located slidably within the bore (42), the spool valve (60, 160) activated by a lever (31, 131) recevied within and opening (67, 167) of the spool valve (60, 160). One end of the spool valve (60, 160) has a pair of washers (74, 76) disposed thereabout with a spring member (80, 180) located about the spool valve (60, 160) and between the washers (74, 76), and a stop sleeve (82, 182) located about the spool valve (160, 60). The spool valve (60, 160) includes a chamfered groove (61) engaging a check valve (50, 150) within the supply port (47, 147). Displacement of the lever (31, 131) effects axial displacement of the spool valve (60, 160) which opens the check valve (50, 55) to permit hydraulic fluid pressure to be communicated to be bore (42) and with the apply and release ports (44, 144, 48, 148) corresponding to the direction of axial displacement of the spool valve (60, 160).

摘要： The ultrasonic hydraulic booster pump (10, 150) comprises a backing plate housing (11) defining a cavity (14) closed at one end (13) by an end cap (18), the end cap (18) having an inlet port (20) and the backing plate housing (11) having an outlet port (16). A diaphragm (30) having a plurality of openings (33) is mounted between the end cap (18) and a spacer member (35) located within the cavity. A plurality of annular shaped piezoelectric rings or discs (60) are located within a ring housing (40) disposed within the spacer member (35). A plug member (50) with a through opening (52) extends through a central through opening (44) in the ring housing (40) and includes a valve seat (58) disposed closely adjacent a solid central portion (34) of the diaphragm (30), and the end cap (18) includes a valve seat (22) disposed closely adjacent the opposite side of the diaphragm (30). An alternating voltage applied to the piezoelectric rings (60) causes excitation thereof and resonance of the diaphragm (30) so that hydraulic fluid is pumped from the inlet port (20) and out the outlet port (16). The ultrasonic hydraulic booster pump (150) provides increased or boost pressure in a hydraulic braking system (100).
